42-6y=0

I need three sets of coordinates and the line must be parallel to the x axis.I think the y has to be 7 but I can not come up with 2 more that the equation help me!!!!!! I already missed three of these type questions.

Your equation is the same as y = 7. That line, when plotted, is automatically parallel to the x axis.

Possible pairs of coordinates along the line are:
(-2,7), (0,7) and (10,7)
or (x=anything, 7)
