Hooke's Law States That the Force $F$ Required to Compress or Stretch a Spring (Within Its Elastic

Hooke's Law states that the force $F$ required to compress or stretch a spring (within its elastic limits) is proportional to the distance $d$ that the spring is compressed or stretched from its original length. That is, $F = k d$ , where $k$ is the measure of the stiffness of the spring and is called the spring constant. The table below shows the elongation $d$ in centimeters of a spring when a force of $F$ kilograms is applied.
$\begin{array}{|c|c|}\hline \text { Force, } \boldsymbol{F} & \text { Elongation, } \boldsymbol{d} \\\hline 20 & 3.5 \\\hline 40 & 6.3 \\\hline 60 & 10.0 \\\hline 80 & 13.3 \\\hline 100 & 16.5 \\\hline\end{array}$

Find the equation of the line that seems to best fit the data.

A) $F = 12.098 d$
B) $F = 3.024 d$
C) $F = 6.049 d$
D) $F = 4.537 d$
E) $\quad F = 7.561 d$
