A point has an x-coordinate equal to 0. Where must that point lie?

AOn the y-axis
BOn the x-axis
CAt the origin only
DIn Quadrant I only
Answer & Solution
Correct answer: A. On the y-axis
1. The rule for axis points states that an x-coordinate of 0 places the point on the y-axis. 2. The point only sits at the origin if its y-coordinate is also 0, so it is not guaranteed to be exactly at the origin. 3. Quadrants require both coordinates to be nonzero, so a point with x equal to 0 cannot be inside a quadrant. _Source: OpenStax Prealgebra (CC BY 4.0), Ch 11 "Graphs", section 11.1 Use the Rectangular Coordinate System_
