[latex]f egin{array}{lllll} &x_1&y_1&x_2&y_2\ % (a,b) &({{ -1}}quad ,&{{ -7}})quad % (c,d) &({{ 3}}quad ,&{{ 9}}) end{array} \\\ % slope = m slope = {{ m}}= cfrac{rise}{run} implies cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}implies cfrac{9-(-7)}{3-(-1)}implies cfrac{9+7}{3+1}[/latex]

slope = (y2-y1) / (x2-x1) slope = (9-(-7)) / (3-(-1)) slope = 16 / 4 slope = 4
