Find the distance between (3,4) and the line 4x + 3y + 6 = 0.
(3,4) and 4x + 3y + 6 = 0
distance = l 4(3) + 3(4) + 6 l l 30 l 30
_________________ = _______ = ____ = 6 units
sqrt ( 4^2 + 3^2 ) sqrt (25) 5
I would like to note that this works in general; CPhill's method can always be used, it is a formula.
