Write an equation of the line in slope intercept form that pass through the two

mrs_skeptik [129]

$\bf (\stackrel{x_1}{-2}~,~\stackrel{y_1}{15})\qquad
(\stackrel{x_2}{9}~,~\stackrel{y_2}{-18})
\\\\\\
slope = m\implies
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-18-15}{9-(-2)}\implies \cfrac{-33}{9+2}\implies \cfrac{-33}{11}\implies -3
\\\\\\
\begin{array}{|c|ll}
\cline{1-1}
\textit{point-slope form}\\
\cline{1-1}
\\
y-y_1=m(x-x_1)
\\\\
\cline{1-1}
\end{array}\implies y-15=-3[x-(-2)]\implies y-15=-3(x+2)
\\\\\\
y-15=-3x-6\implies y=-3x+9$
