1) By graphing

2) Subsitution

3) Elimination

Ontario curriculum

overall Expectation:

- model and solve problems involving the intersection of two straight lines

specific Expectations:

- solve systems of two linear equations involving two variables, using the algebraic method of substitution or elimination
