Plotting Points on the Coordinate Plane

Front

What is an ordered pair?

Back

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

Front

What does the x-coordinate represent in an ordered pair?

Back

The x-coordinate represents the horizontal position of a point on the coordinate plane.

Front

What does the y-coordinate represent in an ordered pair?

Back

The y-coordinate represents the vertical position of a point on the coordinate plane.

Front

What is the x-axis?

Back

The x-axis is the horizontal line on the coordinate plane where the y-coordinate is zero.

Front

What is the y-axis?

Back

The y-axis is the vertical line on the coordinate plane where the x-coordinate is zero.

Front

How do you plot the point (2, 4) on the coordinate plane?

Back

Start at the origin (0, 0), move 2 units to the right (x-coordinate), and then move 4 units up (y-coordinate).

Front

What is the origin in the coordinate plane?

Back

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

Front

What is the significance of the first number in an ordered pair?

Back

The first number (x-coordinate) indicates the position along the x-axis.

Front

What is the significance of the second number in an ordered pair?

Back

The second number (y-coordinate) indicates the position along the y-axis.

Front

If a point has coordinates (3, 0), where is it located?

Back

It is located on the x-axis, 3 units to the right of the origin.
