![\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}\\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \stackrel{y}{f(x)}= x^2+2 \qquad \begin{cases} x_1=1\\ x_2=2 \end{cases}\implies \cfrac{f(2)-f(1)}{2-1}\implies \cfrac{(2^2+2)-(1^2+2)}{1} \\\\\\ \cfrac{6-3}{1}\implies 3](/tpl/images/0080/6403/d524c.png)
