Let A(3, 2) and B(6, 5) be two points and a point C (x,y) is chosen on the line y=x such that AC+BC is minimum, then the co-ordinates of C are:

(1,1)

(2,2)

(3,3)

(4,4)

Text Solution

Verified by Experts

The correct Answer is:

Reflect A(3,2) in the line y=x to get a point C(2,3). Join BC and find its point of intersection with y=x.
