MTH1W.C3.3
Grade 9 de-streamed — Compare two linear relations, including identifying and interpreting their point of intersection.
A note on this mapping: MTH1W reaches the intersection of two lines graphically only — substitution and elimination are Grade 10 (MPM2D) — so this tag covers the meaning of a solution rather than the method this skill teaches.
The skill that covers it
What a student should be able to do
- Solve a system by substitution.
- Solve a system by elimination.
- Interpret a system with no solution or infinitely many solutions.
- Model two-quantity word problems with a system.
