Plotting Points

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 first number in an ordered pair represent?

Back

The first number (x-coordinate) represents the horizontal position on the coordinate plane.

Front

What does the second number in an ordered pair represent?

Back

The second number (y-coordinate) represents the vertical position on the coordinate plane.

Front

How do you plot the point (-4, -4)?

Back

Start at the origin (0,0), move left 4 units (for -4 on the x-axis), and down 4 units (for -4 on the y-axis).

Front

What is the ordered pair for point E?

Back

(5, 2)

Front

How do you plot the point (4, -12)?

Back

Start at the origin (0,0), move right 4 units (for 4 on the x-axis), and down 12 units (for -12 on the y-axis).

Front

What is the x-coordinate of point K?

Back

3

Front

What is the y-coordinate of point K?

Back

-3

Front

If you have the point (x, y), how do you find the x-coordinate?

Back

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

Front

If you have the point (x, y), how do you find the y-coordinate?

Back

The y-coordinate is the second number in the ordered pair.
