The slope, m,  is the change in y over the change in x between any two points, (x1,y1) and (x2,y2), on the line:
m = (y2-y1)/(x2-x1)
For A = (0,5) and B=(-3,2), we have:
m = (2 - 5)/(-3 - 0) = -3/-3
m = 1
Try it yourself for the other sets of points.

Hello, Amy!
To determine slope, we only need to do the following:
Subtract your second y coordinate from your first y coordinate, then divide by the second x coordinate minus the first x coordinate.
For example: 
Use the formula:  (y2-y1)/(x2-x1).  So, for points A and B, we set it up as (2-5)/(-3-0).  This gives us -3/-3, or 1.  The slope of the line with points A and B is 1.
Hope this helps!
