Question

if the mid point of the line segment joining the point P(6,a-2)and Q(-2,4)is (2,-4) then find the value of a​

Answer 1

Answer: P(6,b-2) Q(-2,4)

Midpoint of PQ = (2,-3)

=> (x1+x2/2,y1+y2/2) = (2,-3)

=> (6-2/2,b-2+4/2) = (2,-3)

=> (4/2,b+2/2) = (2,-3)

Comparing x coordinates,

=> 4/2 = 2

=> 2 = 2

Comparing y coordinates,

=> b+2/2 = -3

=> b+2 = -6

=> b = -8
