what is the relationship between the CO2 concentrate and Photosynthetic rate?

Question

Hey this should help, thanks for trying
  Increasing the CO2 concentration will initially increase the rate of photosynthesis, until other factors become limiting. On a graph of rate of photosynthesis (y-axis) against concentration of CO2 (x-axis), the curve will rise, then level off. At high concentrations, CO2 can become toxic and the rate of photosynthesis may fall.

Photosynthesis takes in CO2 as a reactant in its chemical equation. So as photosynthesis increases, CO2 present in the atmosphere, or in a specifically measured area, will decrease because the photosynthetic rates increase. If plotted on a graph, the X-axis would consist of the photosynthetic rates and the Y-axis would be the CO2 concentration. Therefore you would be able to see a negative slope/trend, meaning that the line will be getting closer to zero.
