Determine if the lines are parallel perpendicular or neither - Choose a point on one of the lines (x1,y1). The distance between the lines is then the perpendicular distance between the point and the other line. If you rewrite the equation of the line in standard form Ax+By=C, the distance can be calculated as: |A*x1+B*y1-C|/sqroot (A^2+B^2).
