Question

Write an equation is slope -intersept form of the line through point (6,-1) with slope m=4.

Answer 1

`\bf (\stackrel{x_1}{6}~,~\stackrel{y_1}{-1})~\hspace{10em} slope = m\implies 4 \\\\\\ \begin{array}c \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-(-1)=4(x-6) \\\\\\ y+1=4x-24\implies y=4x-25`
