A and B
Step-by-step explanation:
Yes. Because rational numbers can be written in a form of fraction and they are integers.

You can see that each time x increases by 1, y increases by 5. This means that the coefficient of x is 5 (if you graphed it, the slope would be 5). To find what value to add at the end, you can look at what y is when x equals 0. In this case, that is -2 (on a graph, -2 would be the y-intercept).
