B.
Step-by-step explanation:
You have to use the number in the variable to figure out if the number multiplied by 3.5 goes over 20 dollars. The highest you can go without going over 20 dollars is 5 notebooks
The point-slope form:

We have the points (3, -4) and (5, 1). Substitute:

The standard form: 
<em>multiply both sides by 2</em>
<em>use distributive property</em>
<em>subtract 2y from both sides</em>
<em>subtract 15 from both sides</em>

<h3>Answer: 5x - 2y = -7</h3>
