Mx+b=y
subtract b from both sides
mx=y-b
divide m in both sides
x=(y-b)/m

Answer: There is increase of 4.255 in the amount of carbon in the atmosphere.
Step-by-step explanation:
Since we have given that
Concentration of carbon in Earth's atmosphere in 1800 = 280 ppm
Concentration of carbon in Earth's atmosphere in 2015 = 399 ppm
We need to find the percentage increase in the amount of carbon in the atmosphere.
So, Difference = 399-280 = 119 ppm
so, percentage increase in the amount of carbon is given by

Hence, there is increase of 4.255 in the amount of carbon in the atmosphere.
