Answer:
Draw all these points and draw a straight line through all of them.
Step-by-step explanation:
y = mx + b
x - 4y = 4
-x -x
-4y = -x + 4
/-4 /-4
y = -1
(0,-1),(4,0),(-8,-3),(-4,-2),(8,1) - The first graph attached
3x+y=-1
y = -3x - 1
(0,-1),(-1,2),(-3,8),(2,-7),(3,-10) - The second/last graph attached.
Hope this helps!
