Coordinate Plane-Graphing Points

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.

Front

What are ordered pairs?

Back

Ordered pairs are pairs of numbers used to represent the position of a point on a coordinate plane, written in the form (x, y). The first number is the x-coordinate, and the second number is the y-coordinate.

Front

What is the x-axis?

Back

The x-axis is the horizontal line on a coordinate plane where the y-coordinate is zero. It runs left to right.

Front

What is the y-axis?

Back

The y-axis is the vertical line on a coordinate plane where the x-coordinate is zero. It runs up and down.

Front

How many quadrants are in a coordinate plane?

Back

There are four quadrants in a coordinate plane, numbered I, II, III, and IV, starting from the upper right and moving counterclockwise.

Front

What are the coordinates of Quadrant I?

Back

In Quadrant I, both x and y coordinates are positive. For example, (3, 2) is in Quadrant I.

Front

What are the coordinates of Quadrant II?

Back

In Quadrant II, the x-coordinate is negative, and the y-coordinate is positive. For example, (-3, 2) is in Quadrant II.

Front

What are the coordinates of Quadrant III?

Back

In Quadrant III, both x and y coordinates are negative. For example, (-3, -2) is in Quadrant III.

Front

What are the coordinates of Quadrant IV?

Back

In Quadrant IV, the x-coordinate is positive, and the y-coordinate is negative. For example, (3, -2) is in Quadrant IV.

Front

What is the origin in a coordinate plane?

Back

The origin is the point where the x-axis and y-axis intersect, represented by the ordered pair (0, 0).
