Coordinate Planes

Front

What is a coordinate plane?

Back

A coordinate plane is 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 a coordinate plane, while the y-axis is the vertical line.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate plane, written in the form (x, y).

Front

What does the point (0,0) represent?

Back

The point (0,0) is called the origin, where the x-axis and y-axis intersect.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they never intersect and are always the same distance apart.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if they intersect at a right angle (90 degrees).

Front

How do you identify a point on the x-axis?

Back

A point on the x-axis has a y-coordinate of 0, so it is in the form (x, 0).

Front

How do you identify a point on the y-axis?

Back

A point on the y-axis has an x-coordinate of 0, so it is in the form (0, y).

Front

What is the significance of the origin in a coordinate plane?

Back

The origin is the starting point for measuring distances on the coordinate plane and is the reference point for all other points.

Front

What is the first number in an ordered pair called?

Back

The first number in an ordered pair is called the x-coordinate.
