Looks like they are looking for the length of the line connecting the two points: (-2,4) and (4,-4).
There is a distance formula you can memorize:
d=sqrt%28%28x%5B2%5D-x%5B1%5D%29%5E2%2B%28y%5B2%5D-y%5B1%5D%29%5E2%29
d=sqrt%28%284-%28-2%29%29%5E2%2B%28-4-4%29%5E2%29
d=sqrt%28%284%2B2%29%5E2%2B%28-4-4%29%5E2%29
d=sqrt%286%5E2%2B%28-8%29%5E2%29
d=sqrt%2836%2B64%29
d=sqrt%28100%29
d=10
