This menas there would be around 8.898% of carbon-14 remaining in the organism.
Answer:
y = -1x + 2
Step-by-step explanation:
We need to find y = mx + b
Use the following equation

Plug in the values
= 
We have found the slope(m) which is -1
We have to find y-int b
Plug in any given x,y into the slope formula
-1 = -1(3) + b
-1 = -3 + b
2 = b
At last the formula is
y = -1x + 2
