3-3: TEKS Practice

  • 1.

    • a. Draw a graph which shows the set of ordered pairs {(1, 4), (2, 4), (3, 8), (4, 10), (5, 12)}.

    • b. Does the set of ordered pairs represent a linear function?

  • 2. The graph of the set of ordered pairs below represents a linear function. Find the rate of change.

    {(1, 6.1), (2, 9.1), (3, 12.1), (4, 15.1)}

  • 3. Does the relation defined by the table represent a linear function?

    • A. Yes, because the rate of change is not constant.

    • B. Yes, because the rate of change is 3.

    • C. No, because the rate of change is 3.

    • D. No, because the rate of change is not constant.

  • 4. Determine whether the relation defined by the table represents a linear function.

    • A. Yes, because the rate of change is 2.6.

    • B. No, because the rate of change is not constant.

    • C. No, because the rate of change is 2.6.

    • D. Yes, because the rate of change is not constant.

  • 5. A student is completing a homework assignment. Each minute, the student records the number of problems left to complete. The table shows the data.

    • a. What is the rate of change of this linear function?

    • b. What does the rate of change represent in this situation?

  • 6.

    • a. Reasoning Does the relation represent a linear function?

      • A. Yes, because the rate of change is not constant.

      • B. No, because the rate of change is not constant.

      • C. Yes, because the rate of change is 3.

      • D. No, because the rate of change is 3.

    • b. If the change in outputs for a relation is not constant, does that mean the relation is not linear? Explain your reasoning.
