This Instructional Activity is a part of the Lesson 10, Unit 2, Grade 8. In this activity, students identify given lines with different slopes and draw a line with a particular slope. For lines D and E as well as the line that students draw, encourage students to draw in slope triangles to help calculate the slope. Monitor for students who draw slope triangles of different sizes and invite them to share during the discussion to reinforce the fundamental idea for this lesson: different slope triangles whose longest side lies on the same line give the same value for slope.
