Answer

Let the mid-point be M(x, y).

The mid-point of the line segment joining the points (-3, 2) and (7, 6) is: Reflection, RSA Mathematics Solutions ICSE Class 10.

By mid-point formula,

(x, y) = (x1+x22,y1+y22)\Big(\dfrac{x1 + x2}{2}, \dfrac{y1 + y2}{2}\Big)

Substituting values we get :

M(x,y)=(3+72,2+62)(42,82)(2,4).\Rightarrow M(x, y) = \Big(\dfrac{-3 + 7}{2}, \dfrac{2 + 6}{2}\Big) \\[1em] \Rightarrow \Big(\dfrac{4}{2}, \dfrac{8}{2}\Big) \\[1em] \Rightarrow (2, 4).

Hence, Option 3 is the correct option.
