Answer:
D
Step-by-step explanation:
 
Using the Slope Equation
Pick two points on the line and determine their coordinates.
Determine the difference in y-coordinates of these two points (rise).
Determine the difference in x-coordinates for these two points (run).
Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope

Answer:
P= -2x +46
Step-by-step explanation:
the relation between price and demand is 
P= mx +b ........................1
when demand is 10 shirts price is $26
when demand is 20 shirts price is $6
firstly put P= 26 and x= 10 in 1 
26= 10m + b.......................2
secondly put x= 20 and P= 6 in 1
6= 20m + b ............................3
solving  2 and 3 we get 
m = -2
putting this value of m in either of 2 and 3 to get b 
b= 46
so the final relation obtained by putting m= -2 and b= 46 in 1 we get 
P= -2x +46
 
        
             
        
        
        
-5x + 5y = 40             -20x +20y =160               -5x + 5(8) = 40
4x + 3y = 24               20x +15y =120                -5x + 40 = 40
                                           35y = 280                   -5x =0
                                               y = 8                         x = 0
