Question

What is the midpoint of a segment with endpoints at (−4, −8) and (8, 10)? A.(−6, −9) B.(−6, 1) C.(2, −9) D.(2, 1)

Answer 1

`\text{The formula of the midpoint of segment AB:}\\\\\left((x_A+x_B)/(2);\ (y_A+y_B)/(2)\right).\\\\\text{We have the points}\ A(-4,\ -8)\ \text{and}\ B(8,\ 10).\ \text{Substitute:}\\\\x=(-4+8)/(2)=(4)/(2)=2\\\\y=(-8+10)/(2)=(2)/(2)=1\\\\Answer:\ \boxed{D.\ (2,\ 1)}`
