This Instructional Activity is a part of the Lesson 12, Unit 4, Grade 8. In this activity, students start with an equation relating distance and time for Han's hike and enough information to write a second equation relating distance and time for Jada's hike. After writing Jada's equation and graphing both lines, students then use the lines to identify the point of intersection and make sense of the point's meaning in the context. This activity is a culmination of student's work writing, solving, and graphing equations along with the thinking they have done on what it means for an equation to be true. From this foundation, students are ready to understand solving systems of equations from an algebraic standpoint in the following lessons. Fluently solving systems algebraically is not expected at this time.
