Rate of Change Calculator
The slope of a line is a rate of change:
                    
                      ( x1 , y1 ) ( x2 , y2
                      )
                    
                  
                    x1 = 
                    
                  
                  
                    y1 = 
                    
                  
                  
                    x2 = 
                    
                  
                  
                    y2 =
