Find the coordinates of foot of perpendicular from the point (2,3) to the line 3x+4y+8=0.

Let the foot of the perpendicular be B (x1, y1).

Equation of given line is

Slope of the line, m = .

As the point B(x1, y1) lies on this line, so it satisfies the equation of line.

Now, slope of line AB =

Since AB is normal to the given line.
