I fail to understand why you have to pay per download even after buying a 40$ card, but the answer that makes the most sense here is 3. You paid a base of 40$ and for each download afterwards you pay one dollar extra, which means that all you do is add 40$ to however much you spent on downloading (which is 1$ y for every 1 x)

the equation for this would be y=x+40 so which ever table fits this equation is correct.

What is the slope of this chart  Zero, Undefined, negative or postive?

Zero

When you move from one x value to the next, there was absolutely no change in the y value, meaning that graphically, the function is a horizontal like at y=-10. X does not affect the y value in any way and thus the slope is 0.
