Answer:
Top left
Step-by-step explanation:
We can plug in the y intercept to find which graph has the correct one.
x = 0 is y intercept
Thus

At this point we known the y intercept is -3 so both graph in the left is considerable.
Notice that the base is the negative, thus the graph would goes down. Therefore the top left would be correct.
40% of 180 is 72
1/4 of 320 is 80
therefore 1/4 of 320 is bigger
4x-9
work shown:
4x+(-7+7-9)
4x+(0-9)
final answer: 4x-9
