Big Ideas: Sometimes equations with an unknown value have no solution. Equations with no solution simplify to the form a = b where a and b are two different real numbers. This lesson gives students experience with linear equations in one variable with no solution. The task asks students to compare two linear expressions set equal to each other. Students create a table and graph to visualize the meaning of their simplified equation in the form of a = b. Vocabulary: no solution, inconsistency Special Materials: graph paper
