Answer 1

Answer:

6/7

Step-by-step explanation:

Product of slope of perpendicular line = -1

Slope = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

          $= \frac{7-0}{3-9}\\\\=\frac{7}{-6}\\\\=\frac{-7}{6}$

Slope of the  perpendicular line = -1/m = -1 ÷ $\frac{-7}{6}$

                                                     $= -1 * \frac{-6}{7} = \frac{6}{7}$
