This is what I said earlier, in the equation y=mx+b, what is m? what does it stand for according to your understanding?
slope is 35
yes, slope is 35. so it means that for 4 hours the charge at 35$ must be 4x35 right?, which means that there is a fixed cost b, which is 200(35 x4) =?
all you need to find is the fixed cost, and identifying your rate ASAP.
SO c= mx +b
c=35x +b (please solve for b )
