Including the bus driver, there are 20 people on a bus. During a one-hour ride, each person produces 740 BTUs (British Thermal U
nits). The interior of the bus measures 38 feet by 8.25 feet by 7.5 feet. How many BTUs per cubic foot are produced? Enter your answer, rounded to the nearest hundredth, in the box.
You take your bus interior and multiply them all together to find the volume. 38 x 8.25 x 7.5 = 2,351.25 Now, you take your 740 BTU and divide by the amount of people (20) 740/20 = 37 So now you divide your volume by the 37 2351.25/37 = 63.55
The -5x is your slope and the 2 is your y-intercept. To graph you just have to make a dot at the 2 on the y line. Next you are going to go up 5 and to the left once. You do the exact opposite going down as well. That will give you a straight line.
