x+y=-4
4x+y=-18

Answer 1

A

Answer 2

B

Answer 3

C

Answer 4

D

Answer 5

the simple thing to do is the find the intercepts

x + y = -4 y- intercept let x = 0 so y = -4 x- intercept let y = 0 so x = -4

so find the graph with a line passing through (-4, 0) and (0, -4)

this will allow you to eliminate some of the choices...

do the same for the other line... and match it to the possible graphs
