You can GRAPH the equation that is given to you. Then, you can use MENU, TRACE, GRAPH TRACE to find the ZERO (X-INTERCEPT).

• A

• B

• C

• D

In order to create a PARALLEL equation you need to use the SAME SLOPE. Find the slope of the graph by using RISE/RUN. Then draw a T-CHART and write down y = mx + b on both sides. Then use the SLOPE and the POINT and plug into the equation to find the b using MENU 3, 1.

OR

You can graph each equation, check to see if it is PARALLEL, and then use MENU, TRACE, GRAPH TRACE to verify it crosses through the given point (9, -2).

Notice the answer choices are written as FACTORS. You can factor this trinomial by using a T-CHART that says Multiply to C | Add to B.
