Question

Find the slope 9,4 and 0,5

Answer 1

$\bf \begin{array}{ccccccccc} &&x_1&&y_1&&x_2&&y_2\\ % (a,b) &&(~{{ 9}} &,&{{ 4}}~) % (c,d) &&(~{{ 0}} &,&{{ 5}}~) \end{array} \\\\\\ % slope = m slope = {{ m}}\implies \cfrac{\stackrel{rise}{{{ y_2}}-{{ y_1}}}}{\stackrel{run}{{{ x_2}}-{{ x_1}}}}\implies \cfrac{5-4}{0-9}\implies \cfrac{1}{-9}\implies -\cfrac{1}{9}$
