# Chapter 8: Equations and Relationships, Grade 8 Math

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 8.3: Creating and Evaluating Algebraic Expressions**

** Support Questions for Section 8.3**

**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.

**Further explanation of the relationship between tables of values, graphs and equations**

**Section 8.5: Solving Equations II**

**Extra Practice for Solving Equations**

**Answers to some of the previous problems**

**Chapter 8 Test Preparation Questions**

**Answer to question 1, addition of question 5**
