Question

find the value of a, for which point p(a/3,2) is the midpoint of the line segment joining the points Q(-5,4) and R(-1,0).

Answer 1

hello users .....

we have given that :
point P ( a / 3 ,2) is the mid point of line joining points Q(-5 ,40) and R( -1 ,0) 

we have to find :
value of a = ? 

solution :-
we know that 
for mid point (x,y)
$x = \frac{ ( x_{1} + x_{2} ) }{2}$ 
and
$y = \frac{( y_{1} + y_{2}) }{2}$ 

here,
a /3 =  {(-5) + (-1)} / 2 
=> a = 3 * ( -3) = -9 answer

Answer 2

The value of a is -9
