Common Core Math - Grade 8
Lesson Plan
Understand that solutions to a system of two linear equations correspond to points of intersection of their graphs
Goals / Objectives
Explain that a solution to a system of two linear equations is an ordered pair (x, y) that makes both equations true simultaneously
Graph two linear equations on the same coordinate plane and identify their point of intersection as the solution to the system
Verify that the intersection point satisfies both equations by substituting its coordinates into each equation
Classify a system of two linear equations by the number of solutions (one solution, no solution, or infinitely many solutions) based on the behavior of the two lines
Explain why graphing can produce imprecise solutions when the intersection point has non-integer coordinates, and recognize the need for algebraic methods
Standards
