Question

if p(a/2,4) is the mid point of the line segment joining the points A(-6,5) and B(-2,3),then find the value of a

Answer 1

Answer:

X = A/2 ; X1 = -6 ; X2 = -2 ; Y = 4 ; Y1 = 5 ; Y2 = 3

P IS MID POINT OF AB

SO, WE KNOW  THE MID POINT FORMULA

===> A+B/2

SO, MID POINT OF AB  = (-6-2)/2 ; 3+5/2

MID POINT OF AB = -8/2 ; 8/2

MID POINT OF AB = -4 ; 4

==> (A/2 , 4 ) = - 4 ; 4

==> A/2 = -4

==> A = -8
