The relationship between the Fahrenheit (F) and Celsius (C) temperature scales is given by the linear function F = 9 5 C + 32. (a) Sketch a graph of this function. (b) What is the slope of the graph? What does it represent? The slope means that F increases degrees for each increase of 1∘C. What is the F-intercept? What does it represent? The F-intercept of is the Fahrenheit temperature corresponding to a Celsius temperature of 0.
