1.	What will be the co-ordinates of foot of perpendicular line drawn from the point (-1,3) to the line 3x-4y-16=0?(a) (1/5,2/5)(b) (2/25,5/25)(c) (68/25,-49/25)(d) (-49/25,68/25)I have been asked this question in final exam.I would like to ask this question from Computational Geometry in portion Computational Geometry of Data Structures & Algorithms II
Answer» Right ANSWER is (c) (68/25,-49/25) The EXPLANATION is: The foot of PERPENDICULAR can be found by equating the DISTANCE between the two points and the distance between point and line. This is found to be (68/25,-49/25).
