M = (y2 - y1) / (x2 - x1)
Call (3,-4) one point
Call (-2,5) the second point.
m = (5- -4) / (-2 - 3)
m = 9/-5 = - 9 / 5
B<<<< answer
Answer:

Step-by-step explanation:
![75-2(9-5)^2+2^3](https://tex.z-dn.net/?f=75-2%289-5%29%5E2%2B2%5E3)
First, solve the parentheses:
![75-2(4)^2+2^3](https://tex.z-dn.net/?f=75-2%284%29%5E2%2B2%5E3)
Next, the exponential terms
![75-2(16)+8](https://tex.z-dn.net/?f=75-2%2816%29%2B8)
Solve the multiplication:
![75-32+8](https://tex.z-dn.net/?f=75-32%2B8)
Add and subtract:
There will be at least 1,350 bacteria in the Petri dish in 3 hours, or at 11:00am.
8:00am: 50 bacteria
9:00am: 150 bacteria
10:00am: 450 bacteria
11:00am: 1350 bacteria
