Question

4) The heat is turned on in a room. After 5 minutes, the temperature is 64 °F and after 25 minutes, the

temperature is 72 °F.
a) Assuming a linear function, write an equation that relates the temperature (F) to the time (t).
Show all work.

Answer 1

F=0.4t

Explanation:

Find the slope using the formula rise over run or y2-y2 over x2-x1

y2=72 y1=64 x2=25 x1=5

72-64/25-5=8/20=0.4
