Hey there !!
there rate of change represent slope 
so here m = 0.5
y intercept = 3
so using this :- y = me+c 
y = 0.5x + 3 
option b is correct
        
             
        
        
        
Answer:
V = 11.4 cubic yards 
Step-by-step explanation:
1 foot = 12 inches
1 yard = 36 inches
1 cubic yard = 46656 cubic inches
change the given values to inches by multiplying by 12
Length = 10'8" , round to higher foot
Length = 11*12  =
Length = 132 inches
Width = 6'4", round to higher foot
Width = 7*12
Width = 84 inches
Depth = 4'
Depth = 4*12 = 48 inches
The volume V = length x width x depth = 132 x 84 x 48 = 532224 cubic inches
divide by 46656 get cubic yards
V = 11.4 cubic yards
