This answer is not correct.

The solubility of a dissolved gas will decrease when the solution is heated. This sounds backwards since we usually heat up a solvent in order to dissolve something. The overall energy of a system is dependent on enthalpy and entropy. Temperature is associated with entropy or randomness. If you heat up a solution of a gas and the gas escapes, the system becomes more random therefore it is favorable to have a decrease in solubility.

This relationship is easy to remember if you think about what happens when you open a container of pop. The carbon dioxide bubbles out of the solution...at times, faster than we want it to...if the container is warm.

The solubility of a gas will decrease when the pressure over the solution is decreased.

This is Henry's law and it is also easy to remember if you think about what happens when you open a container of pop. The carbon dioxide bubbles out of the solution because the pressure within the bottle or can is higher than atmospheric pressure. You have decreased the pressure over the solution.
