Learn how to find the distance between two points by using the distance formula, which is an application of the Pythagorean theorem. We can rewrite the Pythagorean theorem as d=√((x_2-x_1)²+(y_2-y_1)²) to find the distance between any two points. Created by Sal Khan and CK-12 Foundation.

So a slope of -2/3 would go down 2 right 3, and if you applied the negative to the 3 (2/-3), you go up 2 left 3, all points should then be along the same line. So with (-7.-4) you could go <3,-2> to get to (-4,-6), or you could go <-3,2> to get to (-10,-2).
Example. Use the graph to find the slope of the line. Solution. Start from a point on the line, such as [latex](2,1)[/latex] and move vertically until in line with another point on the line, such as [latex](6,3)[/latex]. The rise is 2 units. It is positive as you moved up.

This video tutorial lesson discusses the meaning of slope and the relationship between slope and velocity on a position-time graph. The procedure for calculating slope is clearly explained and modeled using three sample calculations.
