Front

What is the definition of a coordinate plane?

Back

A two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis).

Front

What does the x-axis represent in a coordinate plane?

Back

The horizontal line in a coordinate plane where the y-coordinate is zero.

Front

What does the y-axis represent in a coordinate plane?

Back

Front

If a point (3, 4) is reflected over the y-axis, what is the new coordinate?

Back

(-3, 4)

Front

What is the distance formula used for?

Back

To calculate the distance between two points in a coordinate plane.

Front

What is the formula for the distance between points (x1, y1) and (x2, y2)?

Back
