The coordinates of the foot of the perpendicular from the point `(2,3)

1.	The coordinates of the foot of the perpendicular from the point `(2,3)`on the line `-y+3x+4=0`are given by`((37)/(10),-1/(10))`(b) `(-1/(10),(37)/(10))``((10)/(37),-10)`(d) `(2/3,-1/3)`A. (37,/10,-1/10)B. (-1/10,37/10)C. (10/37,-10)D. (2/3,-1/3)
Answer» Correct Answer - B The line passing through (2,3) and perpendicular to -y+3x+4=0 is `(y-3)/(x-2) =-(1)/(3)` or 3y+x-11 = 0 Therefore, the foot is x=-1/10, y=37/10.
