Coordinate Plane Test

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). Each point on the plane is defined by an ordered pair of numbers (x, y).

Front

What are the four quadrants of a 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

How do you plot a point on the coordinate plane?

Back

To plot a point (x, y), start at the origin (0, 0), move x units along the x-axis (right for positive, left for negative), and then move y units along the y-axis (up for positive, down for negative).

Front

What are the coordinates of the origin?

Back

The coordinates of the origin are (0, 0).

Front

What does it mean for a point to be on the x-axis?

Back

A point is on the x-axis if its y-coordinate is 0, meaning it has the form (x, 0).

Front

What does it mean for a point to be on the y-axis?

Back

A point is on the y-axis if its x-coordinate is 0, meaning it has the form (0, y).

Front

What are the coordinates of a point in Quadrant I?

Back

A point in Quadrant I has positive x and positive y coordinates, such as (3, 4).

Front

What are the coordinates of a point in Quadrant II?

Back

A point in Quadrant II has negative x and positive y coordinates, such as (-3, 4).

Front

What are the coordinates of a point in Quadrant III?

Back

A point in Quadrant III has negative x and negative y coordinates, such as (-3, -4).

Front

What are the coordinates of a point in Quadrant IV?

Back

A point in Quadrant IV has positive x and negative y coordinates, such as (3, -4).
