Question

What is the slope 19,-16 -7,-15

Answer 1

$\bf \begin{array}{lllll} &x_1&y_1&x_2&y_2\\ % (a,b) &({{ 19}}\quad ,&{{ -16}})\quad % (c,d) &({{ -7}}\quad ,&{{ -15}}) \end{array} \\\\\\ % slope = m slope = {{ m}}= \cfrac{rise}{run} \implies \cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{-15-(-16)}{-7-19}\implies \cfrac{-15+16}{-7-19} \\\\\\ \cfrac{1}{-26}\implies -\cfrac{1}{26}$
