# Thread: distance from point to line

1. ## distance from point to line

If the distance from P(6,-2) to the line 4x - 3y - k = 0 is 10 units, find k.

wow im lost, thats all i can say

2. If P(p,q) is a point l: Ax+By+C=0 is a line then the distance from P to l is:
$\frac{{\left| {Ap + Bq + C} \right|}}{{\sqrt {A^2 + B^2 } }}.$
