Distance between two points, d, is given by

where: (x1, y1) = (2, 2) and (x2, y2) = (5, 5)
 
 
        
        
        
Answer:
I don't know if this is what you meant, but it's a linear equation.
 
        
             
        
        
        
5 1/2 + p = 6
subtract 5 /12 from each side
5 1/2  - 5 1/2+ p = 6 - 5 1/2
p = 6 - 5 1/2
borrow from the 6
p = 5 2/2 - 5 1/2
p = 1/2
