Answer:
The primary reason is because the vapor pressure of the water is lowered. The boiling point is reached when the vapor pressure of the liquid equals atmospheric pressure. When NaCl is added, the vapor pressure of the solution is lowered and that means the temperature must now be higher than 100 in order to reach 760 mm Hg.

the vapor pressure of water is affected by the addition of the non-volatile solute, NaCl. ... there are fewer water molecules in the vapor (i.e., lower vapor pressure) above the NaCl solution than in the vapor above pure water
