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,...
