The vapour pressure versus temperature curve for a solution solvent system is shown below : 
 

The boiling point of the solvent is ……  °C.

The boiling point of a liquid is the temperature at which its vapour pressure equals atmospheric pressure (usually 1 atm or 760 mmHg).

Given:

You're shown a vapour pressure vs temperature graph.

Look at the point where the vapour pressure = 760 mmHg.
At that point, the temperature = 82°C.

So: Boiling point = 82°C, because that's the temperature where the vapour pressure of the solvent reaches 760 mmHg.
