Answer:

Step-by-step explanation:
The constant of proportionality is the slope of the line joining the two points
(70,40) and (49,28).
Recall the slope formula:

We substitute the point to get:

<u>Alternatively</u>:
A proportional relation is given by

where k is the constant of proportionality.
Using any point, we substitute and solve for k.


The answer is C. Because it takes 5730 years for half of a sample of carbon-14 atoms to decay. It says that 50% of the carbon atoms have decayed so that means that 5730 years have elapsed for that fossil.
I hope that helps.
