2 Use x 1 y 1 to find the equation that is perpendicular to ax by c 0. Next find the distance between points 1 and 3 using the formula above for D2. The formula is a2 b2 c2.
The Distance Formula itself is actually derived from the Pythagorean Theorem which is.
This is the base with a distance of 3 units. Now imagine two points lets say they are 00 and 34 to keep it simple. 1 Write the equation ax by c 0 in slope-intercept form. Deriving the distance between a point and a line is among of the toughest things you have ever done in life.
