1.If P(a/3 ,4) is the midpoint of the line segment joining the points Q(-6, 5) and R(-2, 3) , then find the value of 'a'.
2.A line intersects y-axis and x-axis at the points Pand Q respectively. If (2,-5)is the midpoint of PQ then find the coordinates of P and Q respectively.
SOLUTION 2)
A line intersects the y axis , then the coordinates of P = (0,y) and x axis, then the coordinates of Q = (x,0)
Now,
