Unit 1 - Linear Systems

By the end of this unit, students will be able to solve a system of linear equations using a variety of strategies, solve problems that are modelled by linear equations or systems of linear equations, and describe the relationship between the number of solutions to a system of linear equations and the coefficients of the equations.

Unit 1 Extra Practice

Some have answers, the rest you can check on Desmos.

Unit 1 Assessment is in-class on the following dates:

Cohort A - Tuesday, September 22nd
Cohort B - Wednesday, September 23rd

Students who utilize the resource room or use extra time from their IEP are strongly recommended to stay in the room and only move to resource once the first 75 minutes have passed. Resource teachers will be checking on us as we work.
