Answer

$P=1.38A-24.04$

Work Step by Step

Using desmos.com, we enter a table (columns labeled as A and P), enter the data points, and in a new cell, enter$\quad P\sim mA+b$ The calculator returns $\left\{\begin{array}{l} m=1.37993\\ b=-24.0358\\ r=0.9436 \end{array}\right.$ where $r$ is the regression cofficient. $r$ is close to 1, indicating a good fit for the data. Rounding coefficients, the regression line is given by $P=1.38A-24.04$
