\bf \begin{array}{lllll} &x_1&y_1&x_2&y_2\\ % (a,b) &({{ 10}}\quad ,&{{ 6}})\quad % (c,d) &({{ 30}}\quad ,&{{ 10}}) \end{array} \\\\\\ % slope = m slope = {{ m}}= \cfrac{rise}{run} \implies \cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{10-6}{30-10}

slope=(y2-y1)/(x2-x1), in this case:

slope=(10-6)/(30-10)

slope=4/20

slope=1/5
