Answer: the y intercept is -5
You can use the slope intercept form to find the answer. Aka y = mx + b
In this equation m is equal to the slope and b is equal to the y-intercept.
We already know the slope, 4. And we have two different point we can choose from. I’ll show how to solve with the first (1,-1) point.

Answer:
5.73 hours
Step-by-step explanation:
70% decay means 30% remains
.3 = (1/2)^(t/3.3)
take the log of both sides
log.3 = t/3.3 * log1/2
Divide both sides by log 1/2
log.3 / log1/2 = t/3.3
use calculator
1.736965594166206 = t/3.3
multiply both sides by 3.3
5.73198646074848 = t
rounded
t = 5.73 hours
