Question

The function h(t) = 2t+70 describes the relationship between the temperature (H, measured in degrees Fahrenheit) and time (t, measured in hours) for a given day in Terre Haute, Indiana. Explain what the slope of the equation tells you about the temperature that day in Terre Haute.

Answer 1

(a) m>0 -> y increases as x increases
(b) m=0 -> y is independent of x
(c) m<0 -> y decreases as x increases
