West Street: 3x+2y=-10

Answer 2

How do I solve this? D:

Answer 3

Hmmm I think you would have to divide all sides by 2y to start off.

Answer 4

okay...

Answer 5

But don't you need to have 2 points to figure out whether it is perpendicular or parallel?

Answer 6

All you want to do is to isolate your y so that at tne end it's:

y=...

Answer 7

...

Answer 8

y=-3/2-5... That's what I got?

Answer 9

><'' I stll cn't figure it out...
