Answer is D.
As M is the midpoint of A and B; denote A(x,y); then x and y have to matched the two equations below:
(x- 3) : 2 = 2 <=> x = 7 and
(y +10) : 2 = 6 <=> y = 2
Conclusion : A (7,2)

Answer:
y = -.5x -.5
Step-by-step explanation:
All you do is plug in the x and y in the point to the equation, y = mx + b. Since the coordinate is (5, -3), this in the equation would look like -3 = -.5(5) +b. (all you need to find is the y-intercept, or b.) Solve it out to get -3 = -2.5 + b. Add 2.5 to each side of the equation, you're left with b = -.5. Now, put that back into the original equation, and get y = -.5x -.5. I think this is right, you can go back through and check once more if you'd like.
