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.

    A graph of a line slanting downward through (0, 4), (1, 2), and (2, 0).

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

    A graph of a line slanting upward through (-8, 0), (0, 3), and (8, 6).

  • 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.
