Question

Select the ordered pairs that are on the x-axis. Choose all that apply.

Answer 1

-4,0 
2,0
both are true because they do not have a y coordinate, meaning they dont move off of the x-axis

Answer 2

Points are expressed in (x,y) format so any point which has a y value of zero lies upon the x axis.  So any point (x,0) is on the x axis.  In this case it would be the points:

(-4,0) and (2,0)
