Answer 2

$\bf slope = {{ m}}= \cfrac{rise}{run} \implies \cfrac{{{ f(x_2)}}-{{ f(x_1)}}}{{{ x_2}}-{{ x_1}}}\impliedby \begin{array}{llll} average\ rate\\ of\ change \end{array}\\\\ -------------------------------$

$\bf f(x)= \cfrac{1}{2}(3)^x \qquad \begin{cases} x_1=0\\ x_2=5 \end{cases}\implies \cfrac{f(5)-f(0)}{5-0} \\\\\\ \cfrac{\frac{1}{2}(3)^5~~-~~\frac{1}{2}(3)^0}{5}\implies \cfrac{\frac{3^5}{2}~~-~~\frac{1}{2}}{5}\implies \cfrac{\frac{243}{2}-\frac{1}{2}}{5} \\\\\\ \cfrac{\frac{243-1}{2}}{\frac{5}{1}}\implies \cfrac{\frac{242}{2}}{\frac{5}{1}}\implies \cfrac{242}{2}\cdot \cfrac{1}{5}\implies \cfrac{242}{10}\implies \cfrac{121}{5}$
