Answer:
The second stove had a higher temperature when the stoves were turned off.
The first stove cooled down at a faster rate.
Step-by-step explanation:
first stove: T(t) = 180 - 2.55t can also be written as T(t) = -2.55t + 180
(180 is the y-intercept; -2.55 is the slope)
second stove = T(t) = mt + 200
(0,200) (40,130)
=
=
= -1.5
T(t) = -1.5t + 200
It is more helpful if you supply the graph and the choices.
