# Rate of Change and Slope

#### Welcome

**Welcome:** Rate of Change and Slope

**Description:**
Linear functions the rate of change is called the slope. The slope of a line is the ratio of the change in
y-values to the change in x-values.
Linear functions have a constant rate of change, meaning values increase or decrease at the same rate over a period of time.

Objectives
Students will be able to
recall the formula for calculating the slope of a straight line,
understand how slope is related to the rate of change of two quantities,
calculate the rate of change of two quantities in a linear relationship given
two points that the line passes through,
an input–output table,
a graph,
determine whether a slope is positive, negative, 0, or undefined,
compare multiple linear relationships and their rates of change.

**Grade Level:** 9-12
