Question

If (3,4) is mid point of the line segment whose one end is (7,-2) then find the coordinate of the other point

Answer 1

Coordinates of midpoint (x, y) = (3, 4)

Coordinates of one end (x1, y1) = (7, -2)

Coordinates of other end = (x2, y2)

Using section formula for mid point:

(x1 + x2)/2 = x

7 + x2 = 3 x 2

x2 = 6 - 7 = -1

(y1 + y2)/2 = y

-2 + y2 = 4 x 2

y2 = 8 + 2 = 10

Coordinates of other end = (-1, 10)

Answer 2

Answer: (-1,10)
