Front

What does 'rise over run' refer to in mathematics?

Back

It refers to the formula for calculating the slope of a line, where 'rise' is the change in the y-coordinate and 'run' is the change in the x-coordinate.

How do you determine if a slope is positive, negative, or undefined?

Back

A slope is positive if it rises from left to right, negative if it falls from left to right, and undefined if the line is vertical.

What is the average rate of change, and how is it calculated?

Back

The average rate of change is calculated as the change in the dependent variable divided by the change in the independent variable over a specified interval.
