Coordinate Plane

Front

What is the coordinate plane?

Back

A two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis).

Front

What are the four quadrants of the coordinate plane?

Back

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 is the x-axis?

Back

The horizontal line on the coordinate plane where y = 0.

Front

What is the y-axis?

Back

The vertical line on the coordinate plane where x = 0.

Front

What are coordinates?

Back

A pair of numbers (x, y) that define a point's position on the coordinate plane.

Front

What does the point (0, 0) represent?

Back

The origin, where the x-axis and y-axis intersect.

Front

How do you reflect a point over the y-axis?

Back

Change the sign of the x-coordinate of the point.

Front

How do you reflect a point over the x-axis?

Back

Change the sign of the y-coordinate of the point.

Front

What is the significance of Quadrant I?

Back

It contains all points where both x and y coordinates are positive.

Front

What is the significance of Quadrant II?

Back

It contains all points where x coordinates are negative and y coordinates are positive.
