Back

9

Front

What is the range of a function?

Back

The set of all y-values.

Front

Find the slope when given the points (2, 3) and (3, 5).

Back

2

Front

Find the slope of the line that is horizontal.

Back

0

Front

Find the slope when given the points (2, 5) and (-3, 5).

Back

0

Front

What is an ordered pair?

Back

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

Front

What is the domain of a function?

Back

The set of all x-values.

Front

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

Back

Slope = (y2 - y1) / (x2 - x1).

Front

What does it mean if a slope is undefined?

Back

The line is vertical, meaning it does not have a defined slope.

Front

What is the slope of a vertical line?

Back

Undefined.
