- 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.
About the Lesson
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.
