Graphing, Reflections, Distance on Coordinate Plane

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).

Front

What does the x-axis represent?

Back

The horizontal axis of the coordinate plane, where the y-coordinate is zero.

Front

What does the y-axis represent?

Back

The vertical axis of the coordinate plane, where the x-coordinate is zero.

Front

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

Back

Change the sign of the y-coordinate of the point.

Front

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

Back

Change the sign of the x-coordinate of the point.

Front

What is the reflection of the point (2, 3) over the x-axis?

Back

(2, -3)

Front

What is the reflection of the point (-4, 5) over the y-axis?

Back

(4, 5)

Front

What is an ordered pair?

Back

A pair of numbers (x, y) that represent a point on the coordinate plane.

Front

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

Back

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