Question

A line passes through the point (-4, -8) and has a slope of -5/4 Write an equation in point-slope form for this line. ​

Answer 1

`(\stackrel{x_1}{-4}~,~\stackrel{y_1}{-8})\hspace{10em} \stackrel{slope}{m} ~=~ - \cfrac{5}{4} \\\\\\ \begin{array} \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}{(-8)}=\stackrel{m}{- \cfrac{5}{4}}(x-\stackrel{x_1}{(-4)}) \implies y +8 = - \cfrac{5}{4} ( x +4)`
