Distance on the 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 are the X-axis and Y-axis?

Back

The X-axis is the horizontal line on the coordinate plane, and the Y-axis is the vertical line.

Front

What is the origin in the coordinate plane?

Back

The point where the X-axis and Y-axis intersect, represented as (0,0).

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 an ordered pair?

Back

A pair of numbers used to locate a point on the coordinate plane, written in the form (X,Y).

Front

What does the point (-1, 7) represent on the coordinate plane?

Back

A point located 1 unit left of the origin and 7 units up.

Front

If you reflect the point (3, -4) over the Y-axis, what is the new ordered pair?

Back

(-3, -4).

Front

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

Back

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

Front

What does it mean to translate a point on the coordinate plane?

Back

To move a point a certain distance in a specified direction without changing its orientation.
