Question

complete the sentence.
on the coordinate plane, the perpendicular number lines are called the ____ and the ____.
x-axis... y-axis
x-coordinate... y-coordinate
ordered pair... origin

Explanation:

To solve this, we analyze each option:

• Option 1: The \( x \)-axis and \( y \)-axis are the two perpendicular number lines in a coordinate plane.
• Option 2: \( x \)-coordinate and \( y \)-coordinate are the values that represent a point's location, not the lines.
• Option 3: An ordered pair is a point's location, and the origin is the intersection of the axes, not the lines themselves.

So the correct option is the first one.

Answer:

A. \( x \)-axis... \( y \)-axis
