Answer:
B (-10,6)
Step-by-step explanation:
Usually you would use a formula, but the fastest way to solve this is by eliminating wrong answers. For the x-value, to get from -2 to -6, you have to add negative four. For the y-value, to get from 10 to 8, you have to subtract 2. Following this pattern, use the coordinates for midpoint to find point B. For the x-value, add -4 to -6 to get -10. For the y-value, subtract 2 from 8 to get 6.
Therefore, your answer is (-10,6)
I know this isn't the normal way to do it but this is how I would approach the question.
