<h2>
Its C. y = 1/4x</h2>
Step-by-step explanation:
Look at the line. See where it attaches at one point and look where it attaches to another, for example, in this expression, it attaches to (0,0) and (4,-1). Then do rise over run, or y over x. This means to do this- y2 - y1 divided by x2 - x1. First, do -1 - 0. Its a double negative, so it becomes positive, thus making it 1 - 0, which is still 1. Then do 4 - 0, which is still 4. Divide 1 by 4, turn it to a fraction, and boom, you've got 1/4x.
