Graphing on the coordinate plane

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface where points are defined by pairs of numbers (x, y).

Front

What does the X-axis represent?

Back

The X-axis is the horizontal line in a coordinate plane.

Front

What does the Y-axis represent?

Back

The Y-axis is the vertical line in a 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 as (x, y).

Front

How do you plot the point (3, 2)?

Back

Start at the origin (0, 0), move right 3 units (x=3), then move up 2 units (y=2).

Front

What is the origin in a coordinate plane?

Back

The origin is the point where the X-axis and Y-axis intersect, represented as (0, 0).

Front

What does the point (-2, 3) represent?

Back

Move left 2 units (x=-2) and up 3 units (y=3) from the origin.

Front

What is the purpose of the coordinate plane?

Back

The coordinate plane is used to graph points, lines, and shapes in mathematics.

Front

What does it mean to move 'down' in the coordinate plane?

Back

Moving 'down' means decreasing the y-coordinate value.

Front

What does it mean to move 'right' in the coordinate plane?

Back

Moving 'right' means increasing the x-coordinate value.
