Question

if the point (x, y) is on the y - 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 y - axis is defined as the set of all points where the x - coordinate is 0. Points on the y - axis have the form (0, y), where y can be any real number.

Answer:

$x = 0$
