Question 1 Find the value of a, for which point P (๐/3 , 2) is the mid-point of the line segment joining the points Q(โ5,4) and R(โ1,0). Given P is the mid-point of QR So, x-coordinate of P = (๐ฅ_1 + ๐ฅ_2)/2 Putting x1 = x-coordinate of Q = โ5 x2 = x-coordinate of R = โ1 So, our equation becomes ๐/3 = ((โ5) + (โ1))/2 ๐/3 = (โ5 โ 1)/2 ๐/3 = (โ6)/2 ๐/3 = โ3 a = โ3 ร 3 a = โ9 Thus, a = โ9
