Solving Systems Graphically
Intersection points, number of solutions, and graphing technology.
Overview Solving Systems Graphically (Grade 10) — Unit Overview
This Grade 10 unit teaches learners to solve a system of two linear equations by graphing both lines and interpreting their intersection. The learner distinguishes among one solution, no solution, and infinitely many solutions, and uses graphing technology appropriately while judging when a graphical answer is exact and when it is only an estimate.
