We can just look for the point of intersection between y 3x 2 and the line that is perpendicular to y 3x 2 and passing through 5 1 The line that is perpendicular to y 3x 2 is given by y -13x b. First construct the vertical and horizontal line segments passing through each of the given points such that they meet at the 90-degree angle. Consider a point P in the Cartesian plane having the coordinates x 1y 1.
Now learn how to derive the distance formula in geometry.
If the line passes through two points P 1 x 1 y 1 and P 2 x 2 y 2 then the distance of x 0 y 0 from the line is.
