Answer: A. The cost is $2.00 before any miles are driven
=======================================================
Explanation:
x = number of miles driven
y = total cost of driving x miles
When x = 0, the graph shows y = 2. This is shown as the point (x,y) = (0,2). This is the y intercept where the graph crosses the vertical y axis.
When x = 0, the taxi hasn't driven at all. So having y = 2 pair with this x value means that it costs $2 to get into the cab, even if the cab hasn't gone anywhere. This is the initial fee.

Extra info:
Computing the slope of this line will get you the amount of money per mile charged. In other words, it will give how much extra money you pay per mile on top of the initial $2. In this case, the slope is 9/10 = 0.90, meaning that you pay 90 cents per mile.
The equation of this line is y = 0.90x+2
