The question is incomplete as the attachment of the prism is not given.
From the attachment:
-- Length
-- Width
-- Height

Determine the volume
So, the volume is:



M=change in y/change in x
Finding gradient of the orginal line
=3+1/0-3
=-4/3
Since parallel lines are equal the other line would be -4/3 (gradient)
Sub (-3;2) into y=mx+c
2=-4/3 (-3)+c
2=4+5
2-4=c
-2 = c
Therefore sub all your info and you get y= -4/3x-2
In this question, the profit of the restaurant after t months is given by a polynomial function. To find when it begins to show a profit, we find the numerical values of the function for t, and it shows a profit when 
Profit after t months:

0 months:
This is P(0). So

1 month:
This is P(1). So

2 months:
This is P(2). So

3 months:
This is P(3). So

4 months:
This is P(4). So

5 months:
This is P(5). So

6 months:
This is P(6). So

7 months:
This is `P(7). So

After 7 months it shows profit, so it starts showing profit on the 6th month, and thus, the correct answer is given by option D.
