Question 172167
Since all ordered pairs are in the form (x,y) and x=3, this means that the points are really in the form (3,y). In this case, we can pick ANY y values and the equation will not change. So we can let y=-2, y=1, or y=22 to get the following



(3,-2), (3,1) or (3,22)



which are all solutions to {{{x=3}}}
