1. The second bubble

2. The first bubble.

Step-by-step explanation:

1. If a line has a slope of 0, this means that it is a horizontal line, which means that for any x value, its y value is the same. So, out of your above choices, only B fits.

2. The first bubble because adding and subtracting aren't part of a proportional relationship-
