The key to finding the distance between two points is to remember that the geometric definition of subtraction is the distance between the two numbers as long as we subtract the smaller number from the larger. Find the distance between 11 and 8. The x-value of is negative one.
Find the perpendicular distance from the point to the line by subtracting the values of the line and the x-value of the point.
The distance between two points AxA yA A x A y A and BxB yB B x B y B in two-dimensional Cartesian coordinate plane is the length of the segment connecting them AB dA B xB xA2 yB yA2 A B d A B x B - x A 2 y B - y A 2. To find distance between points Ax_A y_A and Bx_B y_B we use formula. The line is vertical covering the first and fourth quadrant on the coordinate plane. Since this format always works it can be turned into a formula.
