We are using a line regression tool to solve the parameters asked in the problem. We can use online tools or that of Excel. According to the tool, the best fit values are
<span><span> </span><span>Slope0.3848 ± 0.03956
</span><span>Y-intercept0.6053 ± 0.6370
</span><span>X-intercept-1.573
</span><span>1/Slope<span>2.598
Best fit lines make sure that the standard deviation at each point is minimum from the best fit line.</span></span></span>
