Exact Distance (1 Viewer)

[ro_2006]

how do you find the exact distance between a line and a point?

 

[pLuvia]

Using perpendicular distance formula
D=|ax+by+c|/sqrt{a²+b²}

yep wat pLuvia said
the absolute value of the equation of the line is on top with points x and y sub-ed in and then bottom is square root of (a^2 + b^2)
