Let
x-------> the time in minutes
y-------> the temperature in Fahrenheit degrees

we know that
<u>the change in the y-values between two points is equal to</u>

Substitute the y-values of the point A and B in the formula


<u>the change in the x-values between two points is equal to</u>

Substitute the x-values of the point A and B in the formula


therefore
<u>the answer is</u>
The change in the y-value is
and the change in the x-value is 
Here's two. I can't think of any more.
