Edgar is using computer graphics to build the background images for a new
animated film. He is using linear modeling, the process of using linear equations to
describe real-world objects. Edgar has identified the functions needed to build an
image in the graphics program.
Graph each of the following linear functions on the specified domain to build
the image.

y= x + 6 -3 < x < 0
x-4y = 2,2 y=0-2 8y-2x=18,3 x+y=11,4 3x +3y=18,0 y=1/4x+6,0
x=2,0 x=-2,0 x=6,1
all < & > are greater/less than pre equal to.
