Front

What are the coordinates of the origin on a coordinate plane?

Back

(0, 0)

Front

What is the x-axis on a coordinate plane?

Back

The horizontal line that runs left to right.

Front

What is the y-axis on a coordinate plane?

Back

The vertical line that runs up and down.

Front

In which quadrant are both x and y coordinates positive?

Back

Quadrant I (I)

Front

In which quadrant is x negative and y positive?

Back

Quadrant II (II)

Front

In which quadrant are both x and y coordinates negative?

Back

Quadrant III (III)

Quadrant IV (IV)

Front

What does a point with coordinates (a, b) represent on a graph?

Back

A location where 'a' is the x-coordinate and 'b' is the y-coordinate.

Front

What is the distance formula used for in coordinate geometry?

Back

To calculate the distance between two points (x1, y1) and (x2, y2): d = √((x2 - x1)² + (y2 - y1)²).

Front

What is the slope of a line?

Back

The ratio of the rise (change in y) to the run (change in x) between two points on the line.
