You can put this solution on YOUR website! what is the equation of a line through the points (9,3)(5,-5)
-----------
Step 1, find the slope, m
m = diffy/diffx
-----------
Step 2, use the slope and either point y = mx + b to find b, the y-intercept.
----
Then, it's y = mx + b
-------------
Or you can use determinants, my preference.
