If a line segment is drawn between the points (-2,4) and (6,4) then find the coordinates of the point on the same segment which is 4 units from (-2,4).
(2,4)
Given that a line segment is drawn between the points (-2,4) and (6,4).
∵ The Y-coordinates of the points are the same so the line segment is parallel to X-axis.
Let the required point be (x,4)
⇒|x−(−2)|=4(∵ Distance between any two points an a line parallel to x-axis =|x1−x2|)
⇒|x+2|=4
⇒x+2=+4 (or) x+2 -4
⇒x=2 (or)x =-6
∴ Points which are 4 units from (-2,4) are (2,4) and (-6,4)
But (-6,4) doesn't lie on the line segment joining (-2,4) and (6,4)
∴ The required point is (2,4)
