Find the equation for the best fit line, if possible? What information does this line give you? I1. Can you calculate the slope of this line? What information does the slope of the line give you?

Answer 1

The graph is shown in the figure. The equation of the line is given by

Equation y a + bx 0.030-Weight No Weighting Residual 4.6408 Sum of S 2E-6 Pearson' 0.9949 0.025-Adj. R-S 0.9866 ValueStandard nterce -6.48980.0012 Slope 0.504360.02929 0.020 0.015 0.010- 0.005 0.010.020.03 0.040.050.06 E,(J)

Y = a + bx

Where

a = -6.49

b = 0.504

From the plotted data we can find the R square value 0.98 thus the graph is almost fitted

11.

We found the slope of the graph 0.504

The slope of the graph is representing the proportion of the input energy converted into the output energy.
