Front

What is the definition of a coordinate grid?

Back

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

Front

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

Back

The x-axis represents the horizontal number line in a coordinate plane.

Front

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

Back

The y-axis represents the vertical number line in a coordinate plane.

Front

How do you find the distance between two points (x1, y1) and (x2, y2)?

Back

Use the distance formula: Distance = √((x2 - x1)² + (y2 - y1)²).

Front

What happens to the y-coordinate when a point is reflected over the x-axis?

Back

The y-coordinate changes sign.
