M = Midpoint of A and B

Therefore M = ( (8+3)/2 , (6+k)/2) = (5.5 , (6+k)/2)

As y + 3x = 25 intersect at point M, means at point M, it will follow the same equation.

Sub x = 5.5 into the equation to find the value of y at point M.

y = 8.5

sub y into the coordinate of M. y = (6+k)/2

U will get k = 11
