Question

On a coordinate plane, which point lies on the x-axis? A) (0, 10) B) (10, 10) C) (−10, −10) D) (−10, 0)

Answer 1

D.) (-10, 0)

Explanation:

(Important:) When you are looking at coordinate points, remember that inside the parenthesis the number on the left (-10 in this case) is the x-coordinate, and the number on the right (0 in this case) is the y-coordinate.

The reason why point D.) is the correct answer, is because when you have your y-coordinate at 0, it must touch the bottom of the y-axis (or line) in order for it to be on the x-axis. But remember that this specific rule only applies now because the y-coordinate is 0. The letter A.) may look correct because it has a 0, but upon placing it on a graph, we notice that it is on the y-axis and not the x-axis.

I have added an attachment of the graph with all points plotted.

I hope that this helps.
