Which graph models the equation-2x+y=4?

-2x + y = 4 |+2x

y = 2x + 4

for x = 0 → y = 2(0) + 4 = 0 + 4 = 4 → (0; 4)

for x = -2 → y = 2(-2) + 4 = -4 + 4 = 0 → (-2; 4)

factor trees are nice.

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
