Write an equation of a line that does not have a y-intercept

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
