[tex]\begin{gathered} \text{ The equation of the trendline for the data is:} \\ y=5x+23 \end{gathered}[/tex]

The predicted temperature of the substance after 3.5 minutes implies that x =3.5, and we are to find y.

Therefore,

[tex]\begin{gathered} y=5(3.5)+23 \\ y=17.5+23 \\ y=40.5^0C \end{gathered}[/tex]

Therefore, the predicted temperature of the substance, 3.5 minutes after the start of the experiment is 40.5 degrees Celsius
