Question

The length of the perpendicular drawn from the point (-2,1 ) to the line 3 x - 4y - 1 = 0 is
a) - 11 / 5
b) 5 / 11
c) 11 / 5
d) 5 / 11


​

Answer 1

Answer:

Given:

The equation is,

$3x - 4y - 1 = 0$

The point is (-2,1)

The length of the perpendicular drawn from the point is=|ax+by+c|/√a²+b²

=|3x-4y-1|/√3²+4²

=|-6-4-1|/√25

=|-11|/5

=11/5

So the length of the perpendicular drawn to the point is 11/5
