Question 810193: What is the slope of the line that passes through points (12,-8) and (6,-4)
Answer by TimothyLamb(4379)   (Show Source):
You can put this solution on YOUR website! plug the xy pairs into the two-point form:
y - y1 = ( (y2 - y1)/(x2 - x1) )(x - x1)

---
copy and paste the list of xy pairs like so: 12 -8 6 -4
in the two-point input box of the solver, and click the Graph button.
---
the slope is: -0.666666667 or -2/3
