$\bf \begin{array}{lllll} &x_1&y_1&x_2&y_2\\ % (a,b) &({{ -2}}\quad ,&{{ 13}})\quad % (c,d) &({{ -4}}\quad ,&{{ 23}}) \end{array} \\\\\\ % slope = m slope = {{ m}}= \cfrac{rise}{run} \implies \cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{23-13}{-4-(-2)}\implies \cfrac{23-13}{-4+2}$

$\bf y-{{ y_1}}={{ m}}(x-{{ x_1}})\qquad \begin{array}{llll} \textit{plug in the values for } \begin{cases} y_1=13\\ x_1=-2\\ m=\boxed{?} \end{cases}\\ \textit{and solve for$
