Answer:
The slope is 3.
Step-by-step explanation:
y=-1+3x
y=3x-1
y=mx+b where m=slope and b=y-intercept
The number of books that can be shelved is 45. So then we know that the amount that need to be shelved <em>can</em> be 45, if the bookshelf had 0 books on it. This means that it can have the equal part of the inequality sign.
However, the amount of book that need to be shelved cannot <em>exceed</em> 45, so b must be less than 45.
Therefore, the answer must be D) b ≤ 45.
