I know you cant see the graphs but maybe be able to explain a little.

**Reiny**, Monday, September 10, 2012 at 9:55pmI suggest the following:

draw a horizontal axis, called C , for Celsius

draw a vertical axis , called F for Fahrenheit, (note the correct spelling)

label one point as A(50, 122) and another B((100,212)

join with a straight line.

pick any point P(C,F)

slope of PA = slope BA

(F-122)/(C-50) = (212-122)/(100-50)

(F-122)/(C-50) = 90/50 = 9/5

cross-multiply

5F - 610 = 9C - 450**5F = 9C + 160**

F = (9/5)C + 32 or re-arrange to get C = ....

**jay**, Tuesday, September 11, 2012 at 11:02amI believe it would be y=9/5+32 if I made the graph right. Am I close?
