1.5.0 Lesson Overview

In this lesson, you will analyze points on and off a graph and interpret them in context. In explaining correspondences between equations, verbal descriptions, and graphs, you will hone your skill at making sense of problems.

When you finish this lesson, you will be able to:

• Use graphing technology to graph linear equations and identify solutions to the equations.
• Explain how the coordinates of the points on the graph of a linear equation are related to the equation.
• Explain the meaning of points on a graph in terms of the situation it represents when given the graph of a linear equation.

Here are the activities that will help you reach those goals:

• 1.5.1: Analyzing Graphs of Linear Equations
