See the solution process below:

Explanation:

The point-slope formula states: #(y - color(red)(y_1)) = color(blue)(m)(x - color(red)(x_1))#

Where #color(blue)(m)# is the slope and #color(red)(((x_1, y_1)))# is a point the line passes through. Substituting the values from the problem gives:

#(y - color(red)(9)) = color(blue)(-9)(x - color(red)(8))#
