The
slope is the ratio of rise to run.
The
slope is the rate of change of the function at a certain point.
The
slope is the first derivative of a function.
Accordingly, the slope of this line <span>d=420-65t is the coefficient of variable "t" if we consider that d for the dependent variable and t for the independent
Therefore
slope =
- 65</span>
I hope you got
