x = $\frac{60}{9}$ and x = $\frac{45}{8}$

Since in both cases the figures are similar then the ratios of corresponding sides are equal

$\frac{x}{15}$ = $\frac{4}{9}$ ( cross- multiply )

9x = 60 ( divide both sides by 9 )

x = $\frac{60}{9}$

and $\frac{x}{5}$ = $\frac{9}{8}$

8x = 45 ( divide both sides by 8 )

x = $\frac{45}{8}$

$(\stackrel{x_1}{-6}~,~\stackrel{y_1}{-1})\qquad (\stackrel{x_2}{-4}~,~\stackrel{y_2}{2}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{2}-\stackrel{y1}{(-1)}}}{\underset{run} {\underset{x_2}{-4}-\underset{x_1}{(-6)}}} \implies \cfrac{2 +1}{-4 +6} \implies \cfrac{ 3 }{ 2 }$

$\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-1)}=\stackrel{m}{\cfrac{3}{2}}(x-\stackrel{x_1}{(-6)}) \implies {\large \begin{array}{llll} y +1= \cfrac{3}{2} (x +6) \end{array}}$
