Question 1148513
<br>
Note to tutor Shin123....<br>
Showing an answer to a question without showing any work is of no use to the student, assuming the student wants to learn HOW to work the problem.<br>
And in this case you didn't even answer the question, which asked for an equation in slope-intercept form.  Showing a graph of the function without showing the function, and without showing how the profit after 60 months is calculated using that function, is of no use to the student.<br>
You clearly know how to work these problems.  But the purpose of this forum is not to show the student that you know how; the purpose is for you to help the student learn how.<br>
