Question

The temperature in a freezer is falling steadily at a rate of 2°F per minute. The function y=25 -2x gives the temperature y after x minutes. Which set of terms best describes the function y=25-2x in this scenario?

Answer 5

Finally

Answer 6

The equation is
y = 25 - 2x, which can be written as
y = -2x + 25.
That is the equation of a line in slope-interceprt form. That means it is definitly linear.

Answer 7

Also, the rate of the falling tempreature is a continuous rate, so it's also continuous.

Answer 8

Continuous And Linear !
