on the coordinate plane, the number line that runs right and left is the ______.
x - coordinate y - coordinate x - axis y - axis
submit

Explanation:

In a coordinate plane, the x - axis is the horizontal number line that extends from left to right (and also in the opposite direction). The y - axis is vertical (up and down). The x - coordinate and y - coordinate are the values that represent a point's position along the x - axis and y - axis respectively, not the number lines themselves. So the number line that runs right and left is the x - axis.

Answer:

C. x - axis
