Step-by-step explanation:
Distance between points
is given by ![\sqrt{(c-a)^2+(d-b)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28c-a%29%5E2%2B%28d-b%29%5E2%7D)
The trail starts at P(−2, 2) and goes to Q(5, 2).
Take ![(a,b)=(-2,2)\,,\,(c,d)=(5,2)](https://tex.z-dn.net/?f=%28a%2Cb%29%3D%28-2%2C2%29%5C%2C%2C%5C%2C%28c%2Cd%29%3D%285%2C2%29)

It goes from Q to R(5, −5)
Take ![(a,b)=(5,2)\,,\,(c,d)=(5,-5)](https://tex.z-dn.net/?f=%28a%2Cb%29%3D%285%2C2%29%5C%2C%2C%5C%2C%28c%2Cd%29%3D%285%2C-5%29)

It goes from R to S.
Take ![(a,b)=(5,-5)\,,\,(c,d)=(8,-5)](https://tex.z-dn.net/?f=%28a%2Cb%29%3D%285%2C-5%29%5C%2C%2C%5C%2C%28c%2Cd%29%3D%288%2C-5%29)
