Answer 1

the temperature decreases 7 degrees in 3.5 hours. It drops 2 degrees every hour

in one hour it's down 2 degrees

in two hours it's down 4 degrees

in 3 hours, it's down 6 degrees

in 3 1/2 hours it's down 7 degrees

It decreases 1 degree every half hour

change in temperature is -2 degrees per 60 minutes, or -1 degree every 30 minutes

temp = T = initial temperature To - 2(time measured in hours. To = initial temperature

T(t) = To - 2t

If initial temperature is 72 degrees, then T(3.5) = 72-2(3.5) = 72-7 = 65 degrees

assuming a linear relationship

You could graph this as a line, using T temperature on the y axis and t time on the x axis

the line would have a negative slope = -2 and a y-intercept of To.

If To = 72 degrees, then the x intercept is t= 36 hours, when the temperature drops to zero degrees

You might mean something different, but that gives you an equation, a line with slope and intercepts
