Question

if the mid point of the line joining the points P(6, b-3) and Q(-2,3) is (2,-3) then find the value of B​

Answer 1

._____________.______________.

P(6, b-3) (2, -3) Q(-2,3)

(x1,y1) (x ,y) (x2, y2)

• By midpoint Formula

y = (y1 + y2)/2

-3 = [ (b - 3) + 3 ]/2 = (b - 3 + 3)/2

-3 = b/2 •°• b = -6

The value for b is -6
