A student found the slope of a line that passes through the points (1, 14) and (3, 4) to be 5. What mistake did she make?

Respuesta :

well, why don't you tell us what the slope is then?

[tex]\bf \begin{array}{lllll} &x_1&y_1&x_2&y_2\\ % (a,b) &({{ 1}}\quad ,&{{ 14}})\quad % (c,d) &({{ 3}}\quad ,&{{ 4}}) \end{array} \\\quad \\\\ % slope = m slope = {{ m}}= \cfrac{rise}{run} \implies \cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{4-14}{3-1}[/tex]
