Computing Slope: Slope Formula- Sample Problem 1: coordinates-(2,1)(4,3) Sample Problem 2: The only thing you have to watch out with in that formula is that the 1s are from the same point and the 2s are from another.

Using Slope-The way to use slope is rise over run. That means you take the number on top and count up or down that amount, depending on if its positive or negative. Then you take the bottom number and count to the right if its positive and left if its negative. If the line is going down to the right then it is negative. Example 1: y=1x+3 so you start at 3 on the y-axis then count up one and over one and draw a line. If you still don't get it you can use any of these links: [|www.purplemath.com/modules/slope.htm]
