Question

HELP MATHHH Write an equation for the line that is parallel to the given line and passes through the given point. Write your equation in slope-intercept form. y = 4x-3;(-3,12)

Answer 1

Since it's parallel, the slope is the same so it'll be 4
so you plug everything into (y-y1)=m(x-x1)
(y-(12))=(4)(x-(-3))
y-12=4x+12
then you just solve for y

Answer 2

okay thank you so much what about this one
Write the equation of a line that is perpendicular to the given line and that passes through the given point. Write your equation in point-slope form. y-10 =3/2(x-4);(4,2)

Answer 3

Okay since it says perpendicular, the slope must be opposite reciprocal
so the slope for the equation is 3/2
the opposite reciprocal of 3/2 is -2/3
then you just plug everything in (y-y1)=m(x-x1) and solve for y

Answer 4

thanks i plugged the numbers in i have the answer, i really need help on this study guide but im tired so can you help me tomorrow. @m.lupe95

Answer 5

sure like around what time so I can see if I'm able to be on.

Answer 6

anytime is find what time would you like?

Answer 11

I can help! Or try. @bettylee

Answer 12

@nikato pleaseee thanks you

Answer 13

@nikato please helppp

Answer 14

what do you need help on?

Answer 15

What is the slope of a line passing through the pair of points (2, 10) and (8, 3)

Answer 16

Okay you use the slope formula\[\frac{ y2-y1 }{ x2-x1 }\]
plug in the coordinates and what do you get?

Answer 17

yessss how ?

Answer 18

you're given (2,10) and (8,3) so you plug them in into the slope formula i posted
\[\frac{ (10)-(3) }{(2)-(8) }\]

Answer 19

so do i work it out ?

Answer 20

yeah and that's your slope
what did you get?

Answer 21

7/6 ?

Answer 22

Close.. you forgot the negative from (2)-(8).. you get -6

Answer 23

so its 7-6 ?

Answer 24

7/-6 and that's your slope :)

Answer 25

okay thank you can you help me with a few days ?

Answer 26

sure :)

Answer 27

what else do you need help on?

Answer 28

The table shows the number of miles driven over time. Express the relationship between distance and time in simplified form as a unit rate: ___________ mph. Write a statement that interprets the relationship
time- 3 5 7 9
distance-171 285 399 513

Answer 29

okay can I reply back in a little bit?.. I'm in class and I'm going to try to solve it at home

Answer 30

okay that's fine ( :

Answer 31

okay I'm home :) may I ask what topic is this so I review it

Answer 32

well theres not really a topic more like a study guide my teacher just gave us that's due tomorrow and I only have 6 questions out of 17 so its a lot.

Answer 33

Ah..okay well what math are you taking?

Answer 34

im taking algebra 1 right now lol

Answer 35

okay I'm looking through the notes right now :) .. it's been long since I took Algebra and I forgot how to solve this :)

Answer 36

its okay I have a couple more problems also.. its really confusing and im passing with a 92

Answer 37

what other problems do you have? maybe I'll remember some

Answer 38

12) Write each equation in standard form. (Hint: Standard form has three requirements)
a.y=-2/5x+7 B. y=-0.5x+0.9

Answer 39

well for the standard form you use the formula Ax+By=C

Answer 40

soooo that means ?

Answer 41

can you log on tomorrow I have to go

Answer 42

yeah around what time?

Answer 43

what time is good for you ?

Answer 44
