Not quite sure about the endpoint being referred. But see below,
Let's put the given in graph:
--->shown endpoints (7,0) & (0,15)
In this case, to find the "DISTANCE" (green line), we do it thru Distance Formula (variant with Pythagorean Theorem).

Continuing,
d%5E2=%28y%5B2%5D-y%5B1%5D%29%5E2%2B%28x%5B2%5D-x%5B1%5D%29%5E2
d%5E2=%2815-0%29%5E2%2B%287-0%29%5E2=225%2B49=274
highlight%28d=sqrt%28274%29%29, Answer
Thank you,
