This Instructional Activity is a part of the Lesson 27, Unit 4, Grade 8. Does the given system have a solution? The slopes are different, which means they are not parallel and not the same line. Now that we know that the system has a solution, we will solve it without graphing. Notice that in this example we do not have two linear expressions equal to the same number.
