Given information
Given :-
| t (min) | 5 | 10 | 15 | 20 | 25 | 30 |
| V (gal) | 694 | 444 | 250 | 111 | 28 | 0 |
To find :- find the slope of the secant line 
when 
is the point on the graph with 
.
Step-by-step explanation
Step 1.
Consider the table,
| t (min) | 5 | 10 | 15 | 20 | 25 | 30 |
| V (gal) | 694 | 444 | 250 | 111 | 28 | 0 |
Let us find the slopes of the line by using ,
First, calculate 
:
The given point 
:
Then,
Thus, the slope when is
