Choose the equation of the line passing through the point (-2, 4) and perpendicular to y = -one halfx + 4.

Answer 1

y = -x/2 + 4

Slope = -1/2

Since the lines are perpendicular the Product of their slopes = -1

-1/2 * m1 = -1

m1 = 2

Nw using point slope Form (-2, 4)

y - 4 = 2 (x+2)

y = 2x+8

Answer 2

thaNK YOU wanna help with mor yahoo or any one

Answer 3

help Wake Up coffee shop offers two different sizes of coffee. The small coffee costs $2 and the grande coffee costs $3. It is your turn to buy coffee for the office and the bill came to $18. This scenario can be modeled by the equation 2s + 3g = 18. Which is not a possible combination of small and grande coffees?

Answer 4

are there choices?

Answer 5

yes hold on one min

Answer 6

9 small and 1 grande

0 small and 6 grande

3 small and 4 grande

6 small and 2 grande

Answer 7

i think it is c

Answer 8

it's not c

Answer 9

fail lol

Answer 10

it gives you this: 2s + 3g = 18. so for each choice, just substitute and see if it's true or not. the choice that's not true is your answer

Answer 11

for c, 2(3) + 3(4) = 18
6 + 12 = 18
18 = 18, which is true. so it couldn't be c

Answer 12

oh ok never mind then

Answer 13

i came out with a

Answer 14

yup

Answer 15

can u help me with some more i am really bad at math and i am doing practice problems

Answer 16

i'll probably help with one more, but i'm really tired lol. it's 7:25am...haven't slept :l

Answer 17

ohh my you better go sleep i have another person that can help me and just listend to ur thing

Answer 22

lol byyye anD @Shadowys

Answer 23

LOL here! :)

Answer 24

Choose the equation of the line passing through the point (4, -2) and perpendicular to y = one thirdx - 7.

y = -3x - 14

y = 3x - 10

y = -3x + 10

y = 3x + 14

Answer 25

hahahah thank you for helping me my mother is mad i have a 63 im math lol eeeecc

Answer 26

lol that's pretty good actually.
since it is perpendicular, then
\(m_1=\frac{1}{3}\)
\(m_2=-3\) invert and add neg.
passing through (4, -2)
\(y+2 = -3(x-4)\)
which gives
\(y=-3x +10\)
you follow?

Answer 27

yes ok then

Answer 28

hold on

Answer 29

oo yes ok then

Answer 30

Identify the correct slope and y intercept of the equation 3x - 3y = 4.

slope = -1; y intercept at (0, -four thirds)

slope = 1; y intercept at (0, -four thirds)

slope = 3; y intercept at (0, -1)

slope = -3; y intercept at (0, 1)

Answer 31

slope being gradient, so we rearrange that eq.
-3y=-3x+4
\(y=x-\frac{4}{3}\)
so, slope is 1, y intercept is (\(\frac{-4}{3}\),0)

Answer 32

oh i did that backward lol hahah ok i have 3 more lol

Answer 33

ok Identify the correct x intercept and y intercept of the equation x - 2y = 8.

x intercept = (8, 0); y intercept = (0, 4)

x intercept = (8, 0); y intercept = (0, -4)

x intercept = (-8, 0); y intercept = (0, -4)

x intercept = (-2, 0); y intercept = (0, 8)

Answer 34

i think it is b or a

Answer 35

well, when they ask for y intercept, it means the value when x=0.
So, is it b or a? try plugging in x=0 for the y intercept

Answer 36

now im coming out with 2 0 and o 8 negitive

Answer 37

hmm? when x=0, the eq becomes
-2y=8
then y=-4

Answer 38

ohhhhhhh smap never mind oh wow ok lol i skiped like 2 things lol

Answer 39

for this one i came out with a but im not sure its right

Choose the equation of the line passing through the point (1, -5) and parallel to y = 2x + 4.

y = -2x + 7

y = 2x - 3

y = 2x - 7

y = -2x + 3

Answer 40

lol i think you got it?

Answer 41

yayy and one more idk what it is tho

Answer 42

Choose the equation of the line passing through the point (-4, -2) and parallel to y = 1 fourthx + 2.

y = 4x - 1

y = 4x - 3

y = 1 fourthx - 3

y = 1 fourthx - 1

Answer 43

\(y=\frac{1}{4} x +2\)
so the gradient of the next line will also be \(\frac{1}{4}\)
what did you get after applying the formula?

Answer 44

y 4x-

Answer 45

opps 1

Answer 46

eh? lol

Answer 47

am i right lol

Answer 48

or is it 3

Answer 49

Write the equation of the line in slope-intercept form with a slope of -6 and a y-intercept of 9.

Answer 50

heres the last one

Answer 51

Hmm that one isn't perpendicular so actually it should be 4.
\(y+2=\frac{1}{4} (x+4)\)
\(y=\frac{1}{4}x+1-2)\)
\(y=\frac{1}{4}x-1\)

Answer 52

ohh ok and did u see the last question

Answer 53

Write the equation of the line in slope-intercept form with a slope of -6 and a y-intercept of 9.

Answer 54

this would be : y=-6x +9
you follow?

Answer 55

ohhhh lol ok

Answer 56

THANK YOU THANK YOU YOYOUOYOYOUOYOUOYOUO LOL THANK YOU

Answer 57

Answer 64

ok fisrt one

Answer 65

Choose the equation below that represents the line that passes through the point (-2, -1) and has a slope of 5.

y - 1 = 5(x - 2)

y + 1 = 5(x + 2)

y + 2 = 5(x + 1)

y - 2 = 5(x - 1)

Answer 66

ya im virtual schooled

Answer 67

i think its c

Answer 68

hmm, you've got it reversed though, it's the other way around. It's b.

Answer 69

ohh ok next one lol hold on

Answer 70

Choose the equation of the horizontal line that passes through the point (4, -3).

y = 4

x = -3

x = 4

y = -3

Answer 71

s a

Answer 72

opps a

Answer 73

well, the x must equal 4, or y equal -3. once again, you've got it reversed? lol

Answer 74

the coords is (x,y)=(4,-3)

Answer 75

so its b

Answer 76

and it's horizontal, so it should be a y=something. it's y=-3. note the coords

Answer 77

this one again i think is a

Which of the following is the slope between the two points (0, -4) and (-2, 5)?

-nine halves

two ninths

-two ninths

nine halves

Answer 78

yup! this is a

Answer 79

ya yyy lol another one iss lol i think it is a or c again hahah

Choose the slope-intercept equation of the line that passes through the point (-2, 2) and is parallel to y = 4x + 7.

Answer 80

lol options?

Answer 81

heyyyy

Answer 82

y = 4x + 10

y = one fourthx + 5 halves

y = -4x - 6

y = -one fourthx + 3 halves

Answer 83

sorry my computer stoped working

Answer 84

lol yh mine too actually
well, considering that it is parallel, then the gradient must be 4 too. the only option with 4 as gradient is...?

Answer 85

ya

Answer 86

opps a

Answer 87

Choose the slope-intercept equation of the line that passes through the point (6, -6) and is perpendicular to y = 3x - 6.

y = one thirdx - 8

y = -3x + 12

y = 3x - 24

y = -one thirdx - 4

Answer 88

i think it is d

Answer 89

yup, it's a., and yup, it's d. LOL i think you've got it!

Answer 90

ok another one is ,,,,,,,,

Answer 91

now this one i think is c but i really dont knwo


Choose the correct procedure used to graph the equation 3x + 9y = -18 using the intercepts method.

Solve the equation for y to get a y-intercept of (0, -2) and a slope of -one third. Plot the y-intercept, count the slope to get another point and draw the line that passes through the two points.

Choose two different values; plug them into the equation to find the corresponding y-values. Plot the two points and draw the line that passes through the two points.

Let x equal zero and solve for y to find a y-intercept of (0, -2). Let y equal zero and solve for x to find an x-intercept of (-6, 0). Plot the two points and draw a line passing through the two points.

Solve the equation for y to find an intercept of (-2, 0); solve the equation for x to find a y-intercept of (0, -6). Plot the two points and draw a line passing through the two points.

Answer 92

i really dont get this one lol

Answer 93

Well, the intercept form actually means number three lol

Answer 94

ohhhhhhhhh ok nvm next one i got it
Identify the correct slope and y-intercept of the equation 5x - 3y = -6

slope = -5; y-intercept = (0, -6)

slope = five thirds; y-intercept = (0, 2)

slope = -three fifths; y-intercept = (0, 2)

slope = five thirds; y-intercept = (0, -6)

Answer 95

i think its d

Answer 96

you've got the slope right, but the y-intercept can't be -6

Answer 97

ohhhhhhhhhhh c then right

Answer 98

ok next one Choose the equation of the vertical line that passes through the point (-5, 9).

y = -5

y = 9

x = -5

x = 9
