Question 16406
Slope literally means the change in Y over the change in X,( rise over run)or(Delta Y, Delta X)<<< other ways of saying slope.  So, let's make a T chart:
X,Y
1,-2
4,-8
-5,10
3,-6

So, to find the slope of the 1,-2 and 4,-8 we simply do Y2-Y1/X2-X1...where Y2 is -8, Y1 is-2, X2 is 4, and X1 is 1.


-8-(-2)/4-1

By doing the arithmetic we get -6/3, or in lowest terms, -2.  Your slope is negative 2 between the first two ordered pairs.

________

-6-10/3-(-5)

-16/8... answer is also a slope of negative 2 for the second set of ordered pairs.
