EX:

Slope:the ratio between the rise and run between two points of a line! To find the slope between two order pairs, you have to take Y2 and subtract it from Y1 then get X2 then subtract X1 and take both your answers and place em like so Y/X.
      1. Find the slope of (1,2) and (2,1)
      2. Find the slope of (3,4) and (4,3)
      3. Find the slope of (5,6) and (6,5)
 Tip:If you stick to the formula it'll should come easy, make it easy on yourself
