It will be 5x3=15+23=38 so 38 pounds the puppy weigh
        
                    
             
        
        
        
Here is the graph to answer your question. Hope it helped!
 
        
             
        
        
        
33/54 = 44/(a+44)
33(a+44) = 44*54
33a+ 1452 =  2376
33a = 924
    a = 28
c = sqrt (33^2 + 44^2)
c = sqrt(1089 + 1936)
c = sqrt(3025)
c = 55
33/54 = 55/(b+55)
33(b+55) = 55*54
33b+ 1815 =  2970
33b = 1155
    b = 35
answer 
a = 28, b = 35, c = 55
        
             
        
        
        
When comparing the slopes of the functions you must first make y the subject of formula.
6x - y - 2 = 0 => y = 6x - 2 => slope is 6
2y = 3/2 x + 6 => y = 3/4 x + 3 => slpoe = 3/4
5 = 2x + 4y - 3 => 4y = -2x + 5 + 3 = -2x + 8 => y = -1/2 x + 2 => slope = -1/2
The first function is steepest followed by the second function and then the third function.
The slope is not affected by the y-intercept neither is the y-intercept affected by the slope.
