does not have a y intercept is when the line does not pass through the y axis
the only way this can happen if the line is paralell to the y axis (line extends infinitely)
so basically the only way to do this is to do
x=8
x=2
any number except
x=0
so some answers
x=-9
x=-8
x=-7
x=-6
x=-5
x=-4
x=-3
x=-2
x=-1
x=0
x=1
x=2
x=3
x=4
x=5
x=6
x=7
x=8
x=9
x=0.28823487923784
x=-0.923842394
x=-892.98342
x=π
etc
