Algebra 1: Slope as Rate

by Texas Instruments - Action Consequence Lesson
Published on November 30, 2011

Objectives

• Students will be able to interpret the slope of a line as the rate of change of the y-coordinate per unit increase in the x-coordinate as one moves from left to right along the line.
• Students will be able to determine value of the slope of a line from considering the change in y over the change in x between two points on a line.
• Students will be able to use the slope and knowledge of either horizontal or vertical change between two points to determine the other.

Vocabulary

• Ratio
• Slope
• Vertical
• Horizontal
• Rate

This lesson is designed to help students think of slope as a rate of change. As a result, students will be prepared to move to applications of linear functions where the change in one quantity is proportional to the change in another quantity.
