Use the distance formula:
d+=+sqrt%28%28x%5B2%5D-x%5B1%5D%29%5E2%2B%28y%5B2%5D-y%5B1%5D%29%5E2%29 where the x- and y-coordinates of the two given points (-4,5) and (2,-5) provide the x%5B1%5D,y%5B1%5D,x%5B2%5D,andy%5B2%5D respectively.
d+=+sqrt%28%282-%28-4%29%29%5E2%2B%28-5-5%29%5E2%29
d+=+sqrt%28%286%29%5E2%2B%28-10%29%5E2%29
d+=+sqrt%2836%2B100%29
d+=+11.66
Line segment AB is 11.66 units long.
