Answer:
4/9, or 0.4∞
but 0.4∞ has a repeating decimal, so the expanded form is ∞ also
 
        
             
        
        
        
If you could write out the whole problem exactly how it is, I can solve it for you.
        
             
        
        
        
Slope formula;
m = y2 - y1/ x2 - x1     (-2, -1), (3, 4)
m = 4 - (-1)/ 3 - (-2)
m = 5/5
m = 1 
the slope is 1.
hope this helps, God bless!
