Graphing and Slope

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 is an ordered pair?

Back

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

Front

What does the x-coordinate represent?

Back

The horizontal position of a point on the coordinate plane.

Front

What does the y-coordinate represent?

Back

The vertical position of a point on the coordinate plane.

Front

In which quadrant is the point (8, 14) located?

Back

Quadrant I.

Front

In which quadrant is the point (-5, -3) located?

Back

Quadrant III.

Front

What is slope in mathematics?

Back

The measure of the steepness or incline of a line, calculated as the change in y over the change in x (rise/run).

Front

What is a positive slope?

Back

A slope that rises from left to right, indicating that as x increases, y also increases.

Front

What is a negative slope?

Back

A slope that falls from left to right, indicating that as x increases, y decreases.
