Question

Find the coordinates of the midpoint of the line segment joining 

P(–11, –8) and Q(8, –2)

Answer 1

The given points are P(-11,-8) and Q(8,-2).

`x= (x_1 +x_2)/2 , y = (y_1+y_2)/2`

`⇒ x = (-11+8)/2 , y = (-8-2)/2`

`⇒ x = -3/2 , y= -10/2`

` ⇒ x = - 3/2 , y = -5`

Therefore,  `(-3/2,-5)` are the coordinates of midpoint of PQ .
