The slope of the graph should be $30 million / year.  That is, moving one unit along the x-axis to the right should increase the y value by 30 million.

The combined profit in 4 years is $40 million.  That is, the area under the curve from x = 0 to x = 4 should be 40 million.

So, C, right?

ranga · Answer

The small size of the graph makes it hard to read and so I can't tell for sure.  I am unable to read the correct y value for various points on the line.

Based on what you said, I think its C. should I just upload them again, one by one?

ranga · Answer

I am thinking B.   C looks like it has a slope of 20.  It goes from about (0,-40) to (4, 40).  That gives a slope of (40 - -40)/(4-0) = 80/4 = 20

ranga · Answer

B has (0,-80) and (4,40). So slope = (40 - -80) / (4-0) = 120 / 4 = 30.
