Question

Which of the following ordered pairs lies on the y-axis?

ten comma ten

three comma zero

one comma ten

zero comma seven

Answer 1

An ordered pair gives you directions in a coordinate plane: (x,y). It tells you where to go on the x axis and where to go on the y axis. If a point lies on one axis or the other, then either x or y must be 0. So if x is 0, you only go on the y axis and if y is zero, you only travel along the x axis. Hope that helps.

Answer 2

so 0,10?

Answer 3

*0,7?

Answer 4

right, you go over (x) 0 points and up seven which leaves you on the y axis.
