all you have to do here is choose some x values then plot them with the y values you get
choosing values is sort of weird with graphing fractions, but to get whole numbers out, i'd do the following for sure (0 makes the fraction 0, 3 cancels out with the denominator)
(0, y), (3, y), (-3, y)
and from there, just continue picking multiples of 3
(0, y), (3, y), (-3, y), (6, y), (-6, y), (9, y), (12, y)
this would be prettier if i could insert a table but i can't. from here, just plug in your x values to receive your y values. i don't know how many points to plot but your results are
(0, -4), (3, 1), (-3, -9), (6, 6), (-6, -14), (9, 11)
you can get more by following the same process if needed!!
