2x-y=-7
4x-y=-4

Answer 1

@MissyK what's the coefficient of y in both equations?

Answer 2

I don't know o_o It doesn't say..

Answer 3

(–1.5, 4)
(1.5, 10)
(4, –1.5)
(–1.5, –2)

Answer 4

2x-y=-7
-y=-7-2x
y=7+2x
sub that into the second equation

Answer 5

The answer choices.. sorry D:

Answer 6

if you know the points just sub them into both equations, the one that comes out true for both is your solution

Answer 7

I'm sorry.. I wouldn't be here if I knew that much.
