91. Temperature Scales The relationship between the Fahrenheit (F) and Celsius (C) temperature scales is given by the equation F = }C + 32. (a) Complete the table to compare the two scales at the given values. (b) Find the temperature at which the scales agree. [Hint: Suppose that a is the temperature at which the scales agree. Set F = a and C = a. Then solve for a.] F - 30° -20° - 10° 0° 50° 68° 86°

Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
