Find the coordinates of the midpoints of the line segment joining
P(-11,-8) and Q(8,-2)
उत्तर
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 .
