Question

Degrees Fahrenheit follows a periodic pattern. The graph below shows the

temperature over two days, where time t is measured in hours after 12:00
a.m. (midnight) on the first day.
Temperature (in degrees Fahrenheit)

Time (in hours)
Write an equation in terms of y, temperature in
degrees Fahrenheit, and t, time in hours, to represent

Answer 1

Y2-Y1
X2-X1

66-52/15-3

14/12 = simplify to 7/6

Y=7/6x +b

52= 7/6(3) + b
52= 3.5 +b
52-3.5=b
48.5= b

The equation is y=7/6x + 48.5
