Answer:

$y = -\dfrac{5}{6} x -\dfrac{31}{3}$

In order to find equation:

<u>Find slope</u>:

$\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} = \dfrac{rise}{run}$

$\rightarrow \sf slope: \dfrac{-17-(-7)}{8-(-4)}$

$\rightarrow \sf slope: -\dfrac{5}{6}$

Then find equation using:

y - y1 = m(x -x1) where (x1, y1) are points, m is slope

$\sf \rightarrow y - (-17) = -\dfrac{5}{6} (x - 8)$

$\sf \rightarrow y = -\dfrac{5}{6} x + \dfrac{20}{3} -17$

$\sf \rightarrow y = -\dfrac{5}{6} x -\dfrac{31}{3}$
