I'll just help you
to find the slope, it is rise over run, rise/run
y-intercept is where the line crosses the y-axis
slope is positive or negative depending which way it is leaning, if it goes up-to-down from left-to-right that means it is negative, on the other hand, if it goes down-to-up from left-to-right means it is positive
Hope this helps :)

Because i just had to do this on my assignment and got 100
It's a saline solution, commonly used in many ways, primarly in chemistry and medicine (i.e. in intravenous therapy, nasal lavage or in biological and chemical experiments), but also for cleaning new piercings or rinsing contact lenses.
Answer:
See explanation
Explanation:
Now we have, the graph attached.the stable disintegration product of C-14 is N-14.
Then;
Since the mass of C-14 originally present is 64g, at a time t= 17100 years, we will have;
N/No = (1/2)^t/t1/2
N = mass of C-14 at time t
No= mass C-14 originally present
t = time taken for N amount of C-14 to remain
No = mass of C-14 originally present
t1/2 = half life of C-14
N/64 = (1/2)^17,100/5730
N/64 = (1/2)^3
N/64 = 1/8
8N = 64
N = 8 g
