$\bf \begin{array}{llll}
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies &\cfrac{2010-1940}{3.10-0.18}\\
&\qquad \uparrow \\
&\textit{rate of change}
\end{array}$

About 4.17%

Step-by-step explanation:

Given: The price of a gallon of gasoline in 1940 = $0.18

The price of a gallon of gasoline in 2010 = $3.10

Change in period : 2010-1940=70

Change in price over the period : $\$3.10-\$0.18=\$2.92$

Now, the percentage rate of change of price for a gallon of gasoline over this period is given by :-

$\dfrac{\text{Change in price over period}}{\text{Change in period}}\times100\\\\\\=\dfrac{2.92}{70}\times100=4.17142857143
\approx4.17\%$

Hence, the percentage rate of change of price for a gallon of gasoline over this period was 4.17 %.
