Question 840032: Determine the linear function that relates the temperature in degrees Celsius, C, to the temperature in degrees Fahrenheit, F. [Note: At sea level, water freezes at 32°F (0°C) and boils at 212°F (100°C).]
A. F=?
B. Use the above function to determine the Fahrenheit temperature corresponding to 40°C.
Any help is much appreciated!

You can put this solution on YOUR website!
Use the data in the form of two points as ordered pair (C, F):
(0,32) and (100, 212).

Find the equation of the line which contains the points (0, 32) and (100, 212). You will want this in slope intercept form. You already have the vertical axis intercept! You SHOULD know the formula for slope. In a somewhat unfinished manner, the equation is:

highlight%28F=%28%28212-32%29%2F%28100-0%29%29C%2B32%29;
You just need to finish the simplification.
