 Question 33356: I really need help on this problem. Its very confusing to me. The equation that expressed Celsius temperature C in terms of Fehrenheit temperature F is linear. Water freezes at 32 degreesF or 0 degreesC and boils at 212 degreesF or 100 degreesC. Find the linear equation of C in terms of F. Please show me a complete solution so I know how to do this for future reference. Thank You!!!!Answer by stanbon(57290)   (Show Source): You can put this solution on YOUR website!You want C in terms of F or C(F) You have two points: (32,0) and (212,100) The slope is (100-0)/(212-32)= 100/180 = 5/9 Your equation looks line C=mF+b You have values for C,m, and F; solve for b. Using (32,0) you get 0=(5/9)(32)+b b=-17.78 So, C=(5/9)F-17.78 It is easier to remember the following which converts from Celsius to Fahrenheit: F=(9/5)C+32 Cheers, Stan H.
