Graphing on a Coordinate Plane

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis). It is used to locate points using ordered pairs (x, y).

Front

What are the coordinates of the origin in the coordinate plane?

Back

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

Front

How many quadrants are in a coordinate plane?

Back

There are 4 quadrants in a coordinate plane.

Front

What is the x-axis?

Back

The x-axis is the horizontal line in a coordinate plane where the y-coordinate is 0.

Front

What is the y-axis?

Back

The y-axis is the vertical line in a coordinate plane where the x-coordinate is 0.

Front

Which quadrant contains the point (2, -5)?

Back

Quadrant IV contains the point (2, -5).

Front

Which point is on the x-axis?

Back

(12, 0) is on the x-axis.

Front

What does the first number in an ordered pair (x, y) represent?

Back

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

Front

What does the second number in an ordered pair (x, y) represent?

Back

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

Front

What is the significance of the signs in coordinates?

Back

The signs indicate the direction of the point: positive x is right, negative x is left, positive y is up, and negative y is down.
