Question

Which is the point-slope form of an equation for the line that passes through (0, –5) with slope 2?

Answer 1

`\bf (\stackrel{x_1}{0}~,~\stackrel{y_1}{-5})~\hspace{10em} \stackrel{slope}{m}\implies 2 \\\\\\ \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}{(-5)}=\stackrel{m}{2}(x-\stackrel{x_1}{0})\implies y+5=2(x-0)`
