Lesson: Slope and Rate of Change Mathematics

In this lesson, we will learn how to interpret the slope of a straight line as the rate of change of two quantities.

Lesson Plan

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.
