slope of the line connecting the two points (-7,5) and (2,-3)
-----------
slope = [5--3]/[-7-2] = 8/-9 = -(8/9)

Let's define Point 1 as (-7,5) and Point 2 as (2, -3).
.
Then you can say that x%5B1%5D+=+-7 and x%5B2%5D+=+2
.
Similarly you can say that y%5B1%5D+=+5 and y%5B2%5D+=+-3
.
Then the equation for the slope (M) is:
.
M+=+%28y%5B2%5D+-+y%5B1%5D%29%2F%28x%5B2%5D+-+x%5B1%5D%29
.
Now all you have to do is substitute the values identified above to get:
.
M+=+%28-3+-+5%29%2F%282+-%28-7%29%29+=+-8%2F%282+%2B+7%29+=+-8%2F9
.
So the slope is -8%2F9
.
Hope this helps you to see your way through the problem.
