Coordinate Plane, Distance & Reflections

Front

What is the coordinate plane?

Back

A two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis), used to locate points using ordered pairs (x, y).

How do you reflect a point over the x-axis?

Back

Change the sign of the y-coordinate. For example, the reflection of (x, y) is (x, -y).

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

Back

Distance = √((x2 - x1)² + (y2 - y1)²).
