A meteorologist has a long-term data set on the carbon dioxide concentration in theatmosphere. From the start of 2002 to the start of 2013, it has increased from 359ppm to392ppm. Write an equation that models how the concentration varies over this time and drawthe graph.

Can anyone give me pointers on how to start working this out. Ive been over my lecture note and still suck. any help would be greatly appreciated.

You have two points [(0,359), (11,392)].

You can draw many (infinite) types graphs through those points.

Easiest graph would be a straight line (y = mx+b)
