maths problem

If we plot degrees Centigrade (C) on the x axis and degrees fahrenheit (F) on the y axis, the graph for converting from one scale to the other is a straight line. Given that 100 C is the same as 212 F and 50 C is the same as 122 F  find the equation of the line in the form F= mC +b, where m and b are constants.

I'm thinking of directly proportional but I feel confused
