Answer 2

Step-by-step explanation:

The given points are (-8,4) and (-2,a).

The distance between these two points of given as 10. So,

$\sqrt{ {( - 2 + 8)}^{2} + {(a - 4)}^{2} } = 10 \\ {6}^{2} + {(a - 4)}^{2} = {10}^{2} \\ 36 + {(a - 4)}^{2} = 100 \\ {(a - 4)}^{2} = 100 - 36 = 64 \\ {(a - 4)}^{2} = {8}^{2} \\ a - 4 = 8 \: or \: a - 4 = - 8 \\ a = 12 \: or \: a = - 4$

So, option 2 is the right answer.
