You can put this solution on YOUR website! Lets look at it this way
endpoint (-1, 13)
midpoint (8, 11)
endpoint (x, y)
---
looking at the x's, we go from -1 to 8. This is a jump of 9, so our next x = 17
looking at the y's, we go from 13 to 11. This is a jump of 2, so our next x = 9
---
Our endpoint is (17,9)
