Question 22653
slope = m

y2-y1
______= slope
x2-x1

take your points  and plug them in to get the slope.  in this example the 1 and the 2's are just letting you know which set of points to use.  1 is the first x or y and 2 is the second .  don't multiply. just put the second set of points in where I have a y2 or x2 and the first in the y1 and x1.  ok  see if that helps
