Q15 of 48 Page 102

One end of a line segment is (4, 0) and mid–point is (4, 1) then find the coordinates of the other end of the line segment.

Let the coordinates of the other end of the line segment be (x, y).


Using the mid–point formula, we get


4 =


⇒ 4 + x = 8


⇒ x = 4


and


1 =


⇒ y = 2


∴ The coordinates of the other end of the line segment are (4, 2).
