Question

Can someone please help??!
What is the solution to the system?

Line 1
x y
–1 9
3 –3
Line 2
x y
–1 –1
2 5
( , )

Answer 1

I think what you are supposed to do is find an equation for each line, then set them equal to each other and solve for x

Answer 2

But how do you do that?? O_O

Answer 3

So to start off, find an equation of a line, either 1 or 2 using the two points given.

Answer 5

Do that first for each line.

Answer 6

Check out that link.

Answer 7

The basic idea is to solve for y = mx + b, you need to find the slope which is M, then use the two points to find "b", then tuhduh you have your equation of a line.

Answer 8

Ok

Answer 9

Oh ok, I'm gonna try and work this out, thank you!

Answer 10

Once you do that, you need to set them equal to each other and solve for x. So come back here with both equations if you don't know how to do that.
