Answer:
Alright, here is the formula.
m = (y2 -- y1) / (x2 -- x1)
So, now we have to take the points and replace them with the variables.
m = (1 - 2) / (-2 - 4)
Great! So now, we have to solve.
1 - 2 = -1
-2 - 4 = -6
So now, it would be:
-1/6
That is the slope! Hope this helps! :)
The highest common factor is 7:
49=7*7
84=7*12
91=7*13
