Using Graphs to Solve Systems of Linear Equations

We used the handheld computers to graph pairs of linear equations from last night's homework and then used the trace function to determine the coordinates of the point of intersection. This is the basis of today's lesson--graphing intersecting lines and reading the intersection point from the graph.

Tonight's Homework: Read Lesson 7.1, and then do problems 17 - 19, 20 - 32, FCO but not 29, and problem 41. Enjoy the little blue sticky notes!
