Slope from two points.

If you are given to find slope above what should you do? 

Well let me teach you, to find slope in graph you need to find the change in Y over the change in X or rise/run.   

So we had given the first plot is (-9,-6) and second is (3,-9) 

So first we find the change in Y and the change in X. 

Change in Y = Y1 – Y2 

Change in X = X 1 – X 2 

We have and equation the find the difference, So plug the number that was given in to the equation above. 

We have  (-9,-6) and (3,-9)  

The change in Y = -6 -(-9) 

                                Y  = 3 

The change in X = -9 – 3 

                               X = -12 

So then we get -3/12 which is simplify to -1/4. 



Math class

In math class we are using this incredible website call Khanacademy to learn. Khan provide us many subjects and level. They have Algebra,Trigonometry, AP and so on. Which is really helpful for us, if we don’t understand the content in class we can practice on our own then watch the video that they provide us. If we still not clear about the subject we can come back and discuss in class or with our teacher.
