Short answer

The required solution is

Step-by-step solution

Step 1. Given Information 

We are given a system of linear inequalities $$\begin{gathered} 4x-5y\le 0 \\ 2x-y\ge 2 \end{gathered}$$and we need to find the solution region of the inequalities.

Step 2. Graphing the inequalities   

First, we plot the equation of the line $4x-5y=0$.

The graph of the inequality $4x-5y\le 0$is a solid line and so is part of the graph of the inequality. Since$\left(0,0\right)$ satisfy the inequality, the graph consists of the portion above the line. The graph is

Again, we plot the equation of the line $2x-y=2$.

The graph of the inequality $2x-y\ge 2$is a solid line and so is part of the graph of the inequality. Since $\left(0,0\right)$does not satisfy the inequality, the graph consists of the portion away from the origin. The shaded portion below the line represents the inequality. The graph is

Step 3. Finding the solution 

The intersection of the shaded regions of the two inequalities gives the result. The required solution is
