Paul says the slope of the line is zero Phoebe says the slope of the line is undefined

A. Paul
B. Phoebe

Why did you use that answer?

B. Phoebe

Step-by-step explanation:

Let's find the slope of the line that passes through (12, 5) and (12, 9).

Slope = = undefined.

14 can't be divided by zero. Therefore, it is concluded that the slope of the line is undefined.

Therefore, Phoebe is correct.

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.

step-by-step explanation:

-2 is the right
