Question

if the point (x, y) is on the x - axis, which of the following must be true? x = 0 y = 0

Explanation:

Step1: Recall coordinate - axis properties

In a two - dimensional Cartesian coordinate system, the x - axis is defined as the set of all points where the y - coordinate is 0. Points on the x - axis have the form (x, 0), where x can be any real number.

Answer:

y = 0
