Solution Steps

Step 1: Identify the given function

The given linear function is: \[ f(x) = 0.015x + 56.45 \] where \( f(x) \) is the average temperature in degrees Fahrenheit, and \( x \) is the number of years after 1900.

Step 2: Substitute \( x = 60 \) into the function

To find \( f(60) \), substitute \( x = 60 \) into the function: \[ f(60) = 0.015(60) + 56.45 \]

Step 3: Calculate the value of \( f(60) \)

Perform the calculation: \[ f(60) = 0.015 \times 60 + 56.45 \] \[ f(60) = 0.9 + 56.45 \] \[ f(60) = 57.35 \]

Step 4: Interpret the result as a point on the graph

The point on the graph corresponding to \( x = 60 \) and \( f(60) = 57.35 \) is: \[ (60, 57.35) \]

Final Answer

The point is \((60, 57.35)\).
