This Instructional Activity is a part of the Lesson 25, Unit 4, Grade 8. Students work independently on Exercises 1-5. The left and right sides of the equation are equal. Could the point be a solution to the system of linear equations? That is, would make both equations true? Why or why not? No. The graphs of the equations represent all of the possible solutions to the given equations. The point is a solution to the equation because it is on the graph of that equation. However, the point is not on the graph of the equation.
