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), used to locate points using ordered pairs (x, y).

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 are the coordinates of the origin?

Back

(0, 0) - the point where the x-axis and y-axis intersect.

Front

What does the x-coordinate represent in a point (x, y)?

Back

The horizontal position of the point on the coordinate plane.

Front

What does the y-coordinate represent in a point (x, y)?

Back

The vertical position of the point on the coordinate plane.

Front

Which quadrant is the point (3, -2) located in?

Back

Quadrant IV.

Front

Which quadrant is the point (-4, 5) located in?

Back

Quadrant II.

Front

What is the reflection of the point (4, 9) over the x-axis?

Back

(4, -9).

Front

What is the reflection of the point (-3, -7) over the y-axis?

Back

(3, -7).

Front

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

Back

The x-coordinate of the point must be 0.
