Question 7 of 15 The temperature in Boston was recorded over a period of five hours. The
equation
y=-3x+49
describes the temperature over this time, where y is the temperature in
degrees Fahrenheit (°F) and x is the number of hours since measurements
started. Which of the following statements correctly describes the
temperature?
A. It was -3°F after five hours, and it is rising by 49 degrees per hour.
B. It was -3°F when the temperature was first measured, and it is
rising by 49 degrees per hour.
C. It was 49°F when the temperature was first measured, and it is
dropping by 3 degrees per hour.
