Question

The graph is blurry but the y axis is going up by 25 and x axis is going up by 1s

Answer 1

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

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

Therefore,

`\begin{gathered} y=5(3.5)+23 \\ y=17.5+23 \\ y=40.5^0C \end{gathered}`

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