Y - 9 = 2(x - 1)
This is because the base equation is below:
y - y1 = m(x - x1)
Answer:
If I'm answering this right, the bus should have travel 36 miles in 60 minutes.
If it takes 20 minutes to get to 12 miles then for every twenty minutes you would just add 12 miles.
You can only cut down a integer number of trees. So you might look at a few integer values for x. As x get large the –x4 term dominates the expression for big losses. x = 0 is easy P(x) = -6. Without cutting any trees you have lost money Put x = 1 and you get for the terms in order -1 + 1 + 7 -1 -6 = 0. So P(x) crosses zero just before you cut the first tree. So you make a profit on only 1 tree. However when x=10 you are back into no profit. So compute a few values for x = 1,2,3,4,5,6,7,8,9.
The answer is B. There are 12 line segments
