Question

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 1

Answer:

D. (2, -1)

Mid point $=({\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}})$

$=({\frac{-5+9}{2},\frac{3+{-5}}{2}})$

$=(4/2,-2/2)$

$=(2, -1)$
