Extra Practice:
Here are a few practice problems. Finding slope will not be on chapter 4 test, but it will be on later tests. Writing an equation with a given graph will be on the test, as will be graphing a line given an equation.
Connecting tile pattern, equation, graph, and table will be on chapter 4 test.
​

• PDF Lesson 4.1.1 to 4.1.7: Multiple Representations
• PDF Lesson 4.1.4 to 4.1.7: Linear Graphs Using y = mx + b

Chapter 4 Test topics will include: 
1. Diamond Problems (see ch 1 and 2)
2. Equations (including distribution)
3. Situation to a rule, tile pattern to a rule, understanding the context of x and y with a rule.
4. Tile pattern --> table --> rule --> graph
5. Is a certain point on the line?
6. Making a table and a graph from a rule.
