the last one?

Answer 3

One slope is positive and one negative. This rules out the top two.

Answer 4

Answer 5

just check the intersection point (1,-2)
which system can apply this point ?

Answer 6

(1,-2) must be a solution to both.

Let's check that last one: 2x - y = 0 ==> 2(1) - (-2) = 2 -(-2) = 2+2 = 4 -- Whoops!

Answer 7

oh okay i see what i did, thanks so much :)

5x - y = 7
2x + y = 0
