Question 139410
The slope is the difference in the y-coordinates divided by the difference in the x-coordinates.


Just calculate {{{((y[1]-y[2])/(x[1]-x[2]))}}} where <big><b>({{{x[1]}}},{{{y[1]}}})</big></b> and <big><b> ({{{x[2]}}},{{{y[2]}}})</big></b> are the ordered pairs representing your points.

 
<big><b>Hint:</big></b> Pay very careful attention to the signs when doing the slope calculation.


For example if you are going to subtract -3 from 3, then it would be {{{3-(-3)=3+3=6}}}.
