Graphing on the Coordinate Plane

Front

What is the coordinate plane?

Back

The 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 ordered pairs?

Back

Ordered pairs are pairs of numbers used to represent the coordinates of a point on the coordinate plane, written in the form (x, y).

Front

What does Quadrant I represent?

Back

Quadrant I is the section of the coordinate plane where both x and y coordinates are positive. It is located in the upper right section.

Front

What does Quadrant II represent?

Back

Quadrant II is the section of the coordinate plane where x coordinates are negative and y coordinates are positive. It is located in the upper left section.

Front

What does Quadrant III represent?

Back

Quadrant III is the section of the coordinate plane where both x and y coordinates are negative. It is located in the lower left section.

Front

What does Quadrant IV represent?

Back

Quadrant IV is the section of the coordinate plane where x coordinates are positive and y coordinates are negative. It is located in the lower right section.

Front

How do you identify the coordinates of a point in Quadrant I?

Back

In Quadrant I, both the x and y values are positive. For example, the point (3, 4) is in Quadrant I.

Front

How do you identify the coordinates of a point in Quadrant II?

Back

In Quadrant II, the x value is negative and the y value is positive. For example, the point (-3, 4) is in Quadrant II.

Front

How do you identify the coordinates of a point in Quadrant III?

Back

In Quadrant III, both the x and y values are negative. For example, the point (-3, -4) is in Quadrant III.

Front

How do you identify the coordinates of a point in Quadrant IV?

Back

In Quadrant IV, the x value is positive and the y value is negative. For example, the point (3, -4) is in Quadrant IV.
