Write an equation of the line passing through (6, -9) and has a slope of -3.


\dashrightarrow\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}

First, we need to write the equation in point-slope form:-


\hookrightarrow\sf{y-y_1=m(x-x_1)}

  • Replace y₁ with -9, m with 3, and x₁ with 6:-


\hookrightarrow\sf{y-(-9)=3(x-6)}


\bigstar On simplification,


\hookrightarrow\sf{y+9=3(x-6)}


\bigstar On further simplification,


\hookrightarrow\sf{y+9=3x-18}


\star Subtract 9 from both sides, which results in:-


\hookrightarrow\sf{y=3x-27}

So we conclude that Option B is correct.

Good luck with your studies.
