Chapter 9 - What to Study

Wednesday we will take our Chapter 9 test. Just like on our practice test, this test will include three major points of study:

Solving equations (don't forget integer rules!)

When solving an equation, perform the opposite operation to both sides of the equation to isolate the variable. If you're solving a two-step equation, add or subtract first; then, multiply or divide to isolate the variable. You can always plug your answer back in to the original equation to check and see if the two sides balance out.

Function Tables

Plug in the values for "x" to solve for "y." Remember your integer rules here as well. Look for a pattern if you are asked to find the function rule (in other words, how are we getting from x to y?).

Graphing Coordinates

For some function tables, you will be asked to graph your (x,y) values as coordinates. Don't forget - walk into the building (right to left) before taking the elevator (up and down).
