The freezing point is the temperature where the two lines intersect.  
Look back at the figure at the bottom of the lab procedures:

and also take a look at the example on the class web page in the LAB 
section.  For each experiment you should have two lines that intersect.  
The temperature at the intersection point is the freezing point.
