It is known that the tensile strength of a plastic increases as a function of the time

Question:

It is known that the tensile strength of a plastic increases as a function of the time it is heat-treated. The following data is collected:

(a) Fit a straight line to this data and use the equation to determine the tensile strength at a time of 32 min.
(b) Repeat the analysis but for a straight line with a zerointercept.
