Question

Measuring Temperature. The two most commonly used scales for measuring temperature are the Fahrenheit and Celsius scales. If you let y denote Fahrenheit temperature and x denote Celsius temperature, you can express the relationship between those two scales with the linear equation y = 32 + 1.8x.

a. Determine b0 and b1.

b. Find the Fahrenheit temperatures corresponding to the Celsius temperatures -40^o, 0^o, 20^o, and 100^o.

c. Graph the linear equation y = 32 + 1.8x, using the four points found in part (b).

d. Apply the graph obtained in part (c) to estimate visually the Fahrenheit temperature corresponding to a Celsius temperature of 28^o. Then calculate that temperature exactly by using the linear equation y = 32 + 1.8x.
