Work Step by Step

Consider the provided condition. It provides an inequality as, $y\ge -3x+2$ Now, calculate the x intercept by substituting y as 0 and converting the greater than symbol to equal to symbol in the above equation. $\begin{align} & \left( 0 \right)=-3x+2 \\ & x=\frac{-2}{-3} \\ & =0.666 \end{align}$ Here, the above substitution gives the coordinate as $\left( 0.666,0 \right)$. Now, calculate the y intercept by substituting x as 0 and converting the greater than symbol to equal to symbol in the above equation. $\begin{align} & y=-3\left( 0 \right)+2 \\ & =2 \end{align}$ Here, the above substitution gives the coordinate as$\left( 0,2 \right)$. The above inequality can be graphed as shown below: The above graph shows the solution region that lies on the right side of the line drawn by the inequality equation.
