Plotting Points and 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 plot points using ordered pairs (x, y).

Front

What are the four quadrants of the coordinate plane?

Back

The four quadrants are: Quadrant I (x > 0, y > 0), Quadrant II (x < 0, y > 0), Quadrant III (x < 0, y < 0), Quadrant IV (x > 0, y < 0).

Front

What does the point (0, 0) represent on the coordinate plane?

Back

The point (0, 0) is called the origin. It is the point where the x-axis and y-axis intersect.

Front

How do you identify the quadrant of a point with positive x and positive y coordinates?

Back

A point with positive x and positive y coordinates lies in Quadrant I.

Front

How do you identify the quadrant of a point with negative x and positive y coordinates?

Back

A point with negative x and positive y coordinates lies in Quadrant II.

Front

How do you identify the quadrant of a point with negative x and negative y coordinates?

Back

A point with negative x and negative y coordinates lies in Quadrant III.

Front

How do you identify the quadrant of a point with positive x and negative y coordinates?

Back

A point with positive x and negative y coordinates lies in Quadrant IV.

Front

What are the coordinates of a point on the x-axis?

Back

The coordinates of a point on the x-axis are of the form (x, 0), where y is always 0.

Front

What are the coordinates of a point on the y-axis?

Back

The coordinates of a point on the y-axis are of the form (0, y), where x is always 0.

Front

What is the significance of the x-axis and y-axis in the coordinate plane?

Back

The x-axis is the horizontal line, and the y-axis is the vertical line. They are used to define the position of points in the coordinate plane.
