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 are the coordinates of the origin?

Back

(0, 0)

Front

What does the x-axis represent?

Back

The horizontal axis in the coordinate plane where y = 0.

Front

What does the y-axis represent?

Back

The vertical axis in the coordinate plane where x = 0.

Front

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

Back

It is located in Quadrant IV.

Front

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

Back

It is located in Quadrant II.

Front

What are the coordinates of POINT C if it is in Quadrant II?

Back

Coordinates will be of the form (-x, +y) where x > 0 and y > 0.

Front

What is the distance formula between two points (x1, y1) and (x2, y2)?

Back

Distance = √((x2 - x1)² + (y2 - y1)²).

Front

What is the midpoint formula between two points (x1, y1) and (x2, y2)?

Back

Midpoint = ((x1 + x2)/2, (y1 + y2)/2).
