Question

What is the equation in standard form of the line which passes through (-2, -3) and has a slope of 1/2? Give a medal to first that answers

Answer 1

@Mertsj

Answer 2

First write the equation of the line in point slope form and then rearrange it.

Answer 3

ok one sec

Answer 4

Point slope form is:
\[y-y _{1}=m(x-x _{1})\]

Answer 5

y-(-3)=1/2x-(-1

Answer 6

i have a few others i need help with

Answer 7

i did that what is next i put it in to standard form but it never matches up with the answers they give you

Answer 8

\[y+2=\frac{1}{2}(x+2)\]

Answer 9

how did you get 2, the y value is -3

Answer 10

can you just do all the steps up to the last one and i can find the answer then

Answer 11

typo

Answer 12

ok thats what i thought

Answer 13

\[y+3=\frac{1}{2}(x+2)\]
\[y+3=\frac{1}{2}x +1\]
\[\frac{1}{2}x-y=2\]

Answer 14

Or sometimes they want it without fractions in which case it would be:
\[x-2y=4\]

Answer 15

so the answer is x-2y=4

Answer 16

To which graph does the point (2, -3) belong?
Choose one answer.
a. y > -x - 2
b. y > -x - 1
c. y > -2x + 3
d. y > -3x + 5

here is another i need help with

Answer 17

Did you plug in 2 for x and -3 for y and see which one is true?

Answer 18

i don't know what i am looking for though

Answer 19

-3>-2-2, -3>-4
Well shazam!! the very first one is true.

Answer 20

ha ha i was right that is what i thought it was 2 more

Answer 21

What is the equation of the line in standard form that passes through the point (3, -2) and is parallel to the line y = -4x + 1?

Answer 22

Do you know that parallel lines have the same slope?

Answer 23

So this is just like the first one with slope = -4

Answer 24

so it would look like y-(-2)=-4(x-3)

Answer 25

\[y+2=-4(x-3)\]

Answer 26

yep. Now rearrange it.

Answer 27

-5x+y=14 is that the answer

Answer 28

\[y+2=-4x+12\]
\[4x+y=10\]

Answer 30

acctually 2 more

Answer 31

What is the equation of the line in slope-intercept form that passes through the point (3, -1) and is perpendicular to the line y = x + 1?

Answer 32

What is the slope of y = x+1?

Answer 33

1

Answer 34

\[y+1=2x-3\]

Answer 35

\[y=2x-4\]

Answer 36

is that the answer

Answer 37

You didn't answer my question. what is the slope of y=x+1?

Answer 38

1

Answer 39

Then what is the slope of the perpendicular?

Answer 40

Hint. It is the negative reciprocal of 1

Answer 41

-1

Answer 42

ok. Now use point slope form and plug in the given point and the slope -1

Answer 43

alright one sec

Answer 44

y+1=-2x+3

Answer 45

\[y+1=-1(x-3)\]
y+1=-x+3
\[y=-x+2\]

Answer 46

y=x+2 is the answer

Answer 47

Did you notice the negative sign in front of the x?

Answer 48

What is the vertex of the graph of y = |x - 2|- 5? last one

Answer 49

yes typo

Answer 50

Remember...the slope of the perpendicular is -1

Answer 51

(2,-5)

Answer 53

never mind thank you so much
