This is Nelson Mathematics 8, Chapter 8: Equations and Relationships. It's one of my favourite chapters, because it really gets students ready for grade 9. Section 8.1: Solving Equations by Graphing

Definitions: Equation, Solution to an equation

Section 8.2: Representing Pattern Relationships

Definitions: Dependent variable, Independent variable, Slope-intercept (y-intercept) form, x-axis, y-axis

Section 8.4: Solving Equations I

We did example 1 by adding the $100 cost of gas to the total cost, then starting at the origin and using a graph to figure out how many lawns we would need to mow to get to $525. If I were to do it again, I would start at -$100 and go to $425, because (1) it's a better model of the situation, and (2) it exposes students to a graph they probably haven't seen before.
