Question 1172220
<pre>
{{{drawing(400,400,-10,10,-10,10,graph(400,400,-10,10,-10,10),
circle(-3,2,.1),line(-15,-27,15,21),locate(-5,3,"(-3,2)"),
locate(4,3,8x-5y-15=0), green(line(-3,2,1.404494382,-0.7528089888)))}}}

You want to find the length of the green line.

The distance from the point (x<sub>1</sub>,y<sub>1</sub>)
to the line Ax+By+C=0 is given by this formula:
d = {{{abs(Ax[1]+By[1]+C)/sqrt(A^2+B^2)}}}

Plug in the formula and simplify.
