Lesson Plan

Number of solutions for systems

Goals / Objectives

Determine whether a system of two linear equations has exactly one solution, no solution or infinitely many, from its slopes and intercepts or from whether one equation is a multiple of the other

Connect each case to intersecting, parallel, or coincident lines

Read the outcome when elimination cancels both variables: a true statement or a false one

Find the value of a parameter for which a system has no solution or infinitely many solutions, using the constants to tell the two apart

Standards

"For a system of linear equations in two variables, determine the conditions under which the system has no solution, a unique solution, or infinitely many solutions."
