I need help finding the slope of the line 
through (4, -1) and (-2, -1)  Thanks!

Just plug 

x1 = 4, y1 = -1, 
x2 = -2, y2 = -1 

into the slope formula:

     y2 - y1
m = --------- 
     x2 - x1

     (-1) - (-1)
m = -------------- 
      (-2) - (4) 

     -1 + 1
m = -------- 
     -2 - 4

      0 
m = ---- 
     -6

m = 0

This means that the line is 
horizontal. Here's its graph:
