Finding the distance between a point and a line actually means find the perpendicular distance from a point to a line.
lesson notes:05 perpendicular distance
All that is needed to find the equation of any line is a point and a slope.
lesson notes:04 point slope formula
Linear functions can be represented by a straight line on the number plane
