Question

if M=(8,5) is the midpoint of the line segment joining v=(9,-8) and w=(a,b) find the coordinates of w?

Answer 1

Answer:

Here is your answer

Step-by-step explanation:

mid pt formula - x1 + x2 ÷ 2 ; y1 + y2 ÷ 2

(8,5) = ( 9 + a / 2 ; -8 + b / 2)

9+a /2 = 8  ;   -8 + b / 2 = 5

a + 9 = 16  ; b - 8 = 5

a = 7 , b = 18

w ( 7,18)
