This tutorial shows how the m = rise/run formula can be generalized to m = (y₂ - y₁)/(x₂ - x₁).

This tutorial discusses what negative reciprocals are and how that relates to slopes of perpendicular line segments.

This tutorial shows how to find the shortest distance from a point to a line using analytic geometry. I have also uploaded another tutorial that demonstrates a method that uses some analytic geometry and some right angled trigonometry.

This tutorial demonstrates a method for finding the shortest distance from a point to a line using some analytic geometry and also right angled trigonometry.

This tutorial shows how to use analytic geometry tools to prove properties related to quadrilaterals.

This lesson will show how to use analytic geometry to determine some properties of triangles through two examples.

This lesson uses two examples to demonstrate how to use the length of a line segment formula.

This lesson demonstrates through 3 examples how to use the midpoint of a line segment formula.
