### 2-6: TEKS Practice

• 1. It costs \$8 to go to a pottery studio. It costs an additional \$2 for each piece you paint.

• a. Complete the table.

• b. Write an equation that shows the relationship between the number of pieces you paint, p, and the total cost, T.

• 2. For a Saturday show, a band receives \$210 plus \$7 for each ticket sold. Write an equation that shows the relationship between the number of tickets sold, t, and the total amount the band receives, P. (Hint: You may find it helpful to make a table that shows values of t and related values of P.)

• 3. Write an equation for the line in slope-intercept form.

• 4. Write an equation in slope-intercept form of the line.

• 5. Use the table to relate the independent variable x to the dependent variable y.

• a. Describe the relationship in words.

• b. Write an equation.

• 6. Suppose each side of a pentagon has length x. Let y be the perimeter of the pentagon. Use the table to relate the independent variable x to the dependent variable y.

• a. Describe the relationship in words.

• b. Write an equation.

• 7. At time x = 0, water begins to drip steadily out of a water tank. After 1 hour, there are 7.9 gallons of water in the tank. After 7 hours, 7.3 gallons remain. Write a linear function rule that models the number of gallons of water y left in the tank for any number of hours x.

• 8. Each month, your phone company charges you a fee of 5 cents per minute as well as a service fee of \$6.95. Write a linear function rule that models the number of dollars y you pay each month for any number of minutes x.
