3y-2x-18

Step-by-step explanation:

We are given with a linear equation 3y-2x -18 . We have to draw this inequality.

In order to draw this inequality , we have to first draw the graph of

3y-2x= -18

Let us do it , by converting the equation into intercept form, and find the x and y intercepts.

Divide both side, each term by -18 , we get

$\frac{3y}{-18}-\frac{2x}{-18}= \frac{-18}{-18}$

$\frac{y}{-6}-\frac{x}{-9}= 1$

$\frac{y}{-6}+\frac{x}{9}= 1$

$\frac{x}{9}+\frac{y}{-6}= 1$

Hence our x intercept = 9

y intercept = -6

Hence the line passes through the coordinates (9,0) and (0,-6). We now plot them on graph and draw our line.

Now we have to check which region to shade.

Our inequality is given as 3y-2x-18

Let us see whether (0,0) satisfies this inequality. For that we need to substitute them in our equation.

3(0)-2(0)-18

0-0-18

0-18

Which is true .

Hence , we shade the region which is containing (0,0) . Also our line need to be broken as it is containing > sign in it.
