gracygirl · Answer

Well your points are...

(-3,6) and (3, -6)
          -6 - 6            -6 - 6                 -12
m = -------- = ------------ = ---------- 
          3 - (-3)          3 + 3                     9


so I believe (I think, I could be wrong.) that it's -12/9

thankyou but you think  its right for sure

Reduce GracyGirl's result, please.  

-12/9 = -??

mathmale · Answer

GracyGirl has used the correct formula for "slope."  You should know this formula by heart.

$$m=slope=\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }$$

gracygirl · Answer

Sorry, should have reduced. Reduced will be -4/3
