Simultaneous Equations
CONCEPTUALUnderstand that two linear equations can be solved simultaneously by finding the point where their graphs intersect, and interpret this graphically and algebraically as the pair of values satisfying both equations
Mastery Evidence
- Explain that the intersection of two lines represents values satisfying both equations
- Find the approximate solution to a pair of simultaneous equations by reading a graph
- Verify a proposed solution by substituting into both equations
Assessment Prompt
“Can [child] explain that solving two equations simultaneously means finding the one pair of values that satisfies both at once — and show what that looks like on a graph?”
Curriculum Standards3 alignments
8.EE.8aCommon Core State Standards for MathematicsAnalyze and solve pairs of simultaneous linear equations. Understand that solutions to a system of two linear equations in two variables correspond to points of intersection of their graphs, because points of intersection satisfy both equations simultaneously.
8.EE.8bCommon Core State Standards for MathematicsAnalyze and solve pairs of simultaneous linear equations. Solve systems of two linear equations in two variables algebraically, and estimate solutions by graphing the equations. Solve simple cases by inspection. For example, 3x + 2y = 5 and 3x + 2y = 6 have no solution because 3x + 2y cannot simultaneously be 5 and 6.
