Find the coordinates of the foot of the perpendicular from the point (-1, 3) to the line 3x – 4y – 16 = 0.

Given: equation is perpendicular from the point (-1, 3) to the line 3x – 4y – 16 = 0.


To find:


The coordinates of the foot of the perpendicular from the point (-1, 3) to the line 3x – 4y – 16 = 0.


Explanation:


Let A ( 1, 3) be the given point.


Also, let M (h, k) be the foot of the perpendicular drawn from A ( 1, 3) to the line 3x 4y 16 = 0


Diagram:



Point M (h, k) lies on the line 3x 4y 16 = 0


3h 4k 16 = 0 … (1)


Lines 3x 4y 16 = 0 and AM are perpendicular.



4h + 3k – 5 = 0 … (2)


Solving eq (1) and eq (2) by cross multiplication, we get:




Hence, the coordinates of the foot of perpendicular are
