Given

The graph is given where x -axis denotes year and y-axis denotes carbon-dioxide in ppm.

Step-by-step explanation

To determine the rate that co2 increases per year .


R=(\Delta CO_2)/(\Delta t)

Substitute the values from the graph.


(1980,340),(2000,380)


\begin{gathered} R=(380-340)/(2000-1980) \\ R=(40)/(20) \\ R=2 \end{gathered}Answer

Hence the rate that co2 increases per year is 2.
