Question

PLEASE HELP IF YOU CAN


I have to write the equation of a line through C that is parallel to Line AB.
The slope of Line AB is -3/4 (the entire thing is negative).

Diagram's in the comments. Please help!

Answer 1

whenever you have to calculate the equation of a line that is parallel to some other line, know that one of the properties of parallel lines is that they have the same slope.
so -3/4 is the slope of line that passes through C.
the form of equation you are going to be working with is:
y=mx+b
now figure out what is given to you and plug the values in.

Answer 2

@cerabear can you do this please so I can help you because I don't just want to give you the answer.

Answer 3

I'm working on it. I'm not good at math okay

Answer 4

alright take your time.

Answer 5

Okay so here's what I did (I don't think I did it the right way)

-3=-3/4(0)+b
And then b=-3

Then I plugged that into the equation like so: y=-3/4x+(-3)

Answer 6

ok so how did you get b=-3?

Answer 7

oh i see you are right

Answer 8

my bad sorry

Answer 9

Anything times zero is zero which got me:
-3=0+b
Then anything plus zero gets zero;
-3=b
Turning it around;
b=-3

Answer 10

you can further simplify your equation:
y=-3/4x+(-3)
to
y=-3/4x-3
and this is your equation. Good job!
