Lesson: Slope of a Line from a Graph or a Table Mathematics • 8th Grade

In this lesson, we will learn how to find the slope of a line using graphs and tables.

Lesson Plan

Students will be able to

understand that the graph of a linear function is a straight line,
link the slope of a line with the rate of change of the function the line represents,
determine the slope of a line from a graph,
determine the slope of a line from a function table.

Q1:

What is the slope of the function represented by the given figure?

Q2:

What is the slope of the function represented by the given figure?

Q3:

Given that the points shown in the table lie on a line, determine the slope of the line.
