Question 26
The boiling point of water is 100C and 212F. The freezing point of water is 0C and 32F.
Can you write an equation for the conversion of the temperature from C to F using this information? (Hint, two points can be expressed on a graph, then one needs to determine the slope = (rise/run) and the Y intercept to form an equation to express one variable in terms of the other)
a) What would be
the Y intercept (b) (when C = 0, what is the value of F)?
b) What is the slope (m) of the line for conversion of C to
F?
c) Express F = mC + b

The boiling point of water is 100oC or 212oF. The freezing point of water is 0oC or 32oF. Follow the steps below to write an equation F = mC +b, for the conversion of the temperature from oC to oF. Write the boiling point and freezing point of water in ordered pairs (oC, oF). Find b by setting C = 0, F =32. Find m by setting C=100, F=212, and using the result from part (b) Express F = mC+b,...
Fahrenheit(F) and Celsius(C) are two temperature units that are related linearly, i.e, one can express one as a linear function of the other. If water boils at 212F and 100C, it freezes at 32F and OC. Find the temperature of 95F in Celsius.
