What is the coordinates of the mid point of the line joining the points (-5, 3) and (9,-5)?

A(7,4)

B(-5, 9)

C(3,-5)

D(2, -1)

Answer:

D. (2, -1)

Read Explanation:

Mid point =(x1+x22,y1+y22)=({\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}})

=(−5+92,3+−52)=({\frac{-5+9}{2},\frac{3+{-5}}{2}})

=(4/2,−2/2)=(4/2,-2/2)

=(2,−1)=(2, -1)
