Note: Options are missing. So, the general solution of the given inequality is shown below.

Given:

The inequality is:

\dfrac{1}{2}(x+2)+3y

To find:

The point lies in the solution set of the given inequality.

Solution:

We have,

\dfrac{1}{2}(x+2)+3y

It can be written as:

\dfrac{1}{2}(x)+\dfrac{1}{2}(2)+3y

\dfrac{1}{2}x+1+3y

\dfrac{1}{2}x+3y

\dfrac{1}{2}x+3y

All the points that satisfy the above inequality are in the solution set of the given inequality.

For example (0,0).

\dfrac{1}{2}(0)+3(0)

0

This statement is true. It means (0,0) is in the solution set.

For example (0,3).

\dfrac{1}{2}(0)+3(3)

9

This statement is false. It means (0,3) is not in the solution set.

The graph of the inequality \dfrac{1}{2}x+3y is shown below.

All the points in the shaded region are in the solution set but the points on the boundary line are not in the solution set.

\\ \sf\longmapsto \dfrac{2}{3}+f=\dfrac{1}{5}

\\ \sf\longmapsto f=\dfrac{1}{5}-\dfrac{2}{3}

\\ \sf\longmapsto f=\dfrac{3-10}{15}

\\ \sf\longmapsto f=\dfrac{-7}{15}
