Grade 8 · Algebra & Patterning
Linear Relations
The equation y = mx + b is one of the most important in all of secondary mathematics. Students learn to read slope as a rate of change and the y-intercept as a starting value. Moving fluidly between table, graph, and equation — and describing what each reveals — is the central skill of this unit.
