Linear interpolation problem:

From Table 1, find the freezing point temperature for a salinity value of 33 using linear interpolation. Also plot the salinity value vs freezing point temperature. Use Excel to plot.

Table 1: Salinity as a function of Freezing temperature

Salinity	Freezing Temperature (F)
0 (fresh water)	32.0
10	31.1
20	30.1
24.7	29.6
30	29.1
35	28.6
