It increases the temperature at which it starts to boil..

When NaCl dissolves in water it splits apart into the Na+ and Cl- ions. Then the colligative (based on amount, not substance) property of boiling point elevation raise the temperature at which the water's vapor pressure equals the atmospheric pressure. This means the water can reach a higher temperature before boiling. (at which point it isn't getting hotter, but merely changing states) Interestingly enough, since its a colligative property that means this same phenomenon occurs with any dissolved substance in water. We do this so the water can reach a higher temperature and thus cook the food quicker. And then after cooking your food, due to the extreme presence of salt in the water, the water explodes, sending hotter than normal boiling water everywhere, including your loved one's thorax.

As NaCl dissolve (table salt) it will lower the temperature of the water and, in the end, stop the boiling. This is because the disassociation of sodium and chlorine is endothermic, which means it take the heat it needs from the environment, that is, the water it is in.

it increases the boiling point of water because salt acts as an impurity

Nothing that I know of. When I make pasta the salt makes the noodles salty and keeps them from sticking together lol
