The equation of line that is parallel to 3x = 2 - 2y and passes through (3, -6) is y = -x - 3

Solution:

Given, line equation is 3x = 2 – 3y

⇒ 3x + 3y = 2 ⇒ (1)

The point is (3, -6)

We have to find the equation of a line which is parallel to given line and passes through given point.

Now, let us find the slope of the given equation


\text { slope }=\frac{-\mathrm{x} \text { coefficient }}{\mathrm{y} \text { coefficient }}=(-3)/(3)=-1

So, slope of line is -1

We also know that, slopes of parallel lines are equal, then slope of our required line is – 1.

Then, let us find our line equation using point slope form


\mathrm{y}-\mathrm{y}_(1)=\mathrm{m}\left(\mathrm{x}-\mathrm{x}_(1)\right)

Where "m" is the slope of the line


\text { Here in our problem, } m=-1,\left(x_(1), y_(1)\right)=(3,-6)

By substituting the values in point slope form we get,


\begin{array}{l}{\rightarrow y-(-6)=-1(x-3)} \\\\ {\rightarrow y+6=-1(x-3)} \\\\ {\rightarrow y=-x-3}\end{array}

Hence the required equation is y = -x - 3
