               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.
