Let h be the numbers of hours, f be the one-time fee and c the cost charged. The equation is
Since you pay $15 per four, plus the fee. We can solve this equation for the fee:
If we plug c=195 and h=9, we have
Is 9.707 greater than 9.717

Since the lines are parallel and you know the slope of 
is -2, you know the slope of line 
will also be -2. You can see on the coordinate grid that line crosses the y-axis at -1. When you piece all of these facts together into slope-intercept form you get = -2x - 1.
