Answer:

Step-by-step explanation:

[tex](x_{1} , y_{1}) = (8 , 9) & (x_{2} , y_{2}) = (14 , -9) \\\\\Slope = \frac{y_{2}-y_{1}}{x_{2}-x{1}}\\\\ = \frac{-9-9}{14-8}\\\\=\frac{-18}{6}\\\\= - 3[/tex]

m = -3 ;  (8 , 9)

[tex]y - y_{1}= m(x - x_{1})\\\\y - 9 = -3(x - 8)\\\\y - 9 = -3x - 8 *(-3) \\\\\\y - 9 = -3x + 24 \\\\\\ y = -3x + 24 + 9\\\\\\ y = -3x + 33[/tex]
