WORKSHEET 4.5: COMPLETING T-TABLES

-------------------------------------------------------------------------------------

Use the following steps to complete a t-table:

1. Determine the values that are provided in the t-table.


2. Substitute one of the given values of the variables in the equation.


3. Solve the equation to find the value of the other variable.


4. Place this value in the t-table.


5. Continue this process until the t-table is complete.

EXAMPLE

Complete the t-table for the equationy= 3 x−8.

Substitute−1forx. Substitute−2fory Completed t-table

y= 3 x− 8 y= 3 x− 8

y=3(−1)− 8 − 2 = 3 x− 8

y=− 3 − 86 = 3 x

y=− 11 2 =x
