What slope is parallel to: m = 3/4?

Back

Parallel lines have the same slope, so the slope is 3/4.

A function is a relation that assigns exactly one output for each input.

Front

How do you determine if a relation is a function from a table?

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x.
