Answer:
first of all the formula
y = mx+c
where m is slope and c is y-intercept.
now substitute the values-
y = 2x - 5
(for the slope here is 2 and the part where the line intercepts y axis is -5
therefore
y = 2x-5
According to the 55 m/min speed, in 3 minutes, he should have traveled 165 m.
Since he only went 135 m, that means the water moved against him for 30 m. That also happened in 3 min so the water is moving against him at 10m/min.

As we can see,
and we need to divide it into 5 subintervals, where

is the length of each interval. Therefore, the subintervals are
![[0,3], [3,6], [6,9], [9,12], [12,15]](https://tex.z-dn.net/?f=%5B0%2C3%5D%2C%20%5B3%2C6%5D%2C%20%5B6%2C9%5D%2C%20%5B9%2C12%5D%2C%20%5B12%2C15%5D)
The midpoint of the first interval is calculated as

Similarly, we obtain that the midpoints of other subintervals are

By the Midpoint rule, we have

From the given data above, we have

Therefore,

I hope this diagram explains it and helps you :)
