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 find the value of y in the equation y = 2x - 2 for x = 1?

Back

Substituting x = 1 gives y = 2(1) - 2 = 0.

Front

What are the values of y for x = 1, 2, 3, 4 in the equation y = 2x - 2?

Back

The values of y are 0, 2, 4, 6.

Front

What is the purpose of a coordinate grid?

Back

A coordinate grid is used to plot points, lines, and shapes in a two-dimensional space.

Front

Which axis runs vertically on a coordinate grid?

Back

The Y-axis runs vertically.

Front

Which axis runs horizontally on a coordinate grid?

Back

The X-axis runs horizontally.

Front

What is the coordinate of point N if it is located at (6, 6)?

Back

The coordinate of point N is (6, 6).

Front

How do you identify a point on a graph using ordered pairs?

Back

You start at the origin (0, 0), move along the x-axis to the x-coordinate, and then move up or down to the y-coordinate.
