Answer:
   y -6 = 1/3(x +3)   or   y = 1/3x +7
Step-by-step explanation:
The slope of the line describing the given path is the x-coefficient, -3. The slope of the perpendicular line will be the negative reciprocal of that:
   m = -1/(-3) = 1/3
The point-slope form of the equation for a line can be used to write the equation for the new path:
   y -k = m(x -h) . . . . . line with slope m through point (h, k)
For m=1/3 and (h, k) = (-3, 6), the new path can be represented by ...
   y -6 = 1/3(x +3) . . . . point-slope form
   y = (1/3)x +7 . . . . . . slope-intercept form
 
        
             
        
        
        
1000 is our constant because the truck was only used one day. We also know they charge a certain amount per hour, but we do not know how much. In this case they charged that amount 9 times because the truck was used for 9 hours. The total of the constant plus the 9hour fee is 2700 dollars:
1000(1) + 9x = 2700
The reason we multiply 1000 by 1, is because we only used the truck for one day.
Solve for x
9x = 2700 - 1000 = 1700
X = 1700/9 = 188.88
The hourly fee is $188.88 
The question is asking for an equation for hours of use though, so the answer is 
1000(1) + 9(188.88) = C
C represents cost or charge.
