About 5 books have been signed out, so they still have 4.
Answer:
<h2>A) y= -x + 1</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line<em>:</em>

<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
The formula of a slope:

==========================================
We have the points (-1, 2) and (4, -3).
Calculate the slope:

Put the value of the slope an the coordinates of the point 9-1, 2) to the equation of a line:

<em>subtract 1 from both sides</em>

Finally:

The opposite of 5 is -5. But if you want the opposite of THAT, then it's 5 again.
Based on your question and based on the graph that you show. I conclude and get an answer that the vertex of the graph is (1,3) and the answer to your second question is maximum. I hope i answer your question directly
