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,

Y=-2x-6+4
Y=-2x-2
Because -1=-2*(1/2)
So y=(1/2)x-2
3=(1/2)*2+b
b=2
So (1/2)x+2
