Question

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

Explanation:

To solve this, we recall the definitions of components on a coordinate plane:

• \(x\)-coordinate: The horizontal value in an ordered pair, not a number line.
• \(y\)-coordinate: The vertical value in an ordered pair, not a number line.
• \(x\)-axis: The horizontal number line on the coordinate plane that runs left - right.
• \(y\)-axis: The vertical number line on the coordinate plane that runs up - down.

So the number line running right and left is the \(x\)-axis.

Answer:

x - axis
