m is the slope
b is the y-intercept
so that means that the y-intercept of

is

(x,y)
y does't change makes it easier
frm 7 to -2
-2-7=-9
distance is 9
Answer: C
Step-by-step explanation:
This describes an expotential function
At t = 0, P = 70
Therefore, C = 70
P = 70 e^kt
Solve for k by plugging in (4,360)
k = 0.4094
plug in t(7 hours)
70 e^(0.4094*7)
The answer roughly equals C
The answer is 54, 5 is 1 more than 4, they equal 9, 54 is 6 times greater than 9
