is the total cost to rent the truck and m is the miles driven. If you plot points on the linear function, which of the following would appear?(1 point)

To determine which points would appear on the linear function \( C = 1.25m + 25 \), we need to substitute the values for \( m \) from the options given and calculate the corresponding values of \( C \).

  1. For the point (30, 4):
    \[ C = 1.25(4) + 25 = 5 + 25 = 30 \]
    So, (30, 4) does not satisfy the equation.

  2. For the point (35, 8):
    \[ C = 1.25(8) + 25 = 10 + 25 = 35 \]
    So, (35, 8) does satisfy the equation.

  3. For the point (2, 22.5):
    \[ C = 1.25(2) + 25 = 2.5 + 25 = 27.5 \]
    So, (2, 22.5) does not satisfy the equation.

  4. For the point (4, 20):
    \[ C = 1.25(4) + 25 = 5 + 25 = 30 \]
    So, (4, 20) does not satisfy the equation.

  5. For the point (4, 30):
    \[ C = 1.25(4) + 25 = 5 + 25 = 30 \]
    So, (4, 30) does satisfy the equation.

  6. For the point (8, 35):
    \[ C = 1.25(8) + 25 = 10 + 25 = 35 \]
    So, (8, 35) does satisfy the equation.

  7. For the point (2, 2.5):
    \[ C = 1.25(2) + 25 = 2.5 + 25 = 27.5 \]
    So, (2, 2.5) does not satisfy the equation.

  8. For the point (4, 5):
    \[ C = 1.25(4) + 25 = 5 + 25 = 30 \]
    So, (4, 5) does not satisfy the equation.

Conclusion: The points (4, 30) and (8, 35) satisfy the equation.

Thus, the response that appears as correct among the given options is:

  • (4, 30) and (8, 35).
