Question

find the value of k 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

hope it will help you..

Answer 2

Answer:

hii

a= -9

Step-b y-step explanation:

coordinate of mid point (x,y)

x = (x1 +x2)/2

y =(y1 +y2)/2

A/q

x =(-5 + (-1))/2 = -3  

⇒a/3 = -3

⇒a =-9

y = (4+0)/2 = 2

coordinate of mid point = (-3,2)

so, a= -9
