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 graph, 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 a graph.

Front

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

Back

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

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-axis), and then move 4 units up (y-axis).

Front

What is the Y-axis?

Back

The Y-axis is the vertical line on a graph where the x-coordinate is 0.

Front

What is the X-axis?

Back

The X-axis is the horizontal line on a graph where the y-coordinate is 0.

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

What does it mean for a point to be in Quadrant I?

Back

A point is in Quadrant I if both its x-coordinate and y-coordinate are positive.

Front

What does it mean for a point to be in Quadrant II?

Back

A point is in Quadrant II if its x-coordinate is negative and its y-coordinate is positive.

Front

What does it mean for a point to be in Quadrant III?

Back

A point is in Quadrant III if both its x-coordinate and y-coordinate are negative.
