To see how the formula that relates Celsius and Fahrenheit temperatures is derived,

Use the equation found in Exercise 101 to find F if C = 15. How does the answer compare with the answer to Exercise 103?

Data from in Exercise 101

Use the slope found in Exercise 100(b) and one of the two points determined earlier, and write an equation that gives F in terms of C.

Data from in Exercise 100(b)

(b) Find the slope of the line passing through these two points.

Data from in Exercise 103

A quick way to estimate Fahrenheit temperature for a given Celsius temperature is to double C and add 30. Use this method to estimate F if C = 15.
