You should understand by now that this is not a homework service nor is it a tutorial service.

The distance from the point $\displaystyle (p,q)$ to the line $\displaystyle Ax+By+C=0$ is

$\displaystyle \displaystyle \frac{|Ap+Bq+C|}{\sqrt{A^2+B^2}}$

Now post some of your own work on this problem.
