The slope intercept form is Y=mx + b
 8x - y - 6=0
<u>-8x          -8x
</u>-y= -6+8x = 0
     <u>+6        +6
</u>-y = 8x + 6

X(30;0)
y(0;50)
substitue 0 for y and solve for x
substitute 0 in for x and solve for y
        
                    
             
        
        
        
Answer:
total bill=1644
let he drives x kilometer
then 
500*2+8*x=1644
1000+8x=1644
8x= 1644-1000
8x= 644
x= 644/8=80.5 km
