Graphing ordered pairs

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 represents the x-coordinate, which indicates the horizontal position on the graph.

Front

What does the second number in an ordered pair represent?

Back

The second number represents the y-coordinate, which indicates the vertical position on the graph.

Front

What is the origin in a coordinate plane?

Back

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

Front

Which axis runs vertically on a graph?

Back

The y-axis runs vertically.

Front

Which axis runs horizontally on a graph?

Back

The x-axis runs horizontally.

Front

How do you plot the point (3, 4) on a graph?

Back

Start at the origin (0, 0), move 3 units to the right (x-coordinate), and then move 4 units up (y-coordinate).

Front

What is the ordered pair for point A located at 4 units right and 3 units up from the origin?

Back

The ordered pair for point A is (4, 3).

Front

If a point is located at (0, 5), what does this indicate?

Back

This indicates that the point is 0 units to the right or left of the origin and 5 units up.

Front

What is the ordered pair for point B located at 2 units left and 2 units down from the origin?

Back

The ordered pair for point B is (-2, -2).
