------------
Solve for y.
Is there some reason you can't do that?

-x+%2B+4y=-16
-x+%2Bx%2B+4y=x-16
4y=x-16
y=x%2F4-16%2F4
y=%281%2F4%29x-4
to graph it, you need two points; find x-intercept and y-intercept
y=%281%2F4%29x-4 set x=0 to find y-intercept
y=%281%2F4%29%2A0-4
y=-4
y-intercept is at (0,-4)

y=%281%2F4%29x-4 set y=0 to find x-intercept
0=%281%2F4%29x-4
4=%281%2F4%29x
4%2A4=x
16=x
x-intercept is at (16,0)
plot these points and draw a line through
