1. **State the problem:** We are given a relation $R$ defined by the inequalities $y \leq x - 2$ and $y \geq 2x - 4$. We need to sketch the graph of this relation.
2. **Understand the inequalities:**
- The first inequality $y \leq x - 2$ represents all points on or below the line $y = x - 2$.
- The second inequality $y \geq 2x - 4$ represents all points on or above the line $y = 2x - 4$.
3. **Graph the boundary lines:**
- For $y = x - 2$, the line has slope 1 and y-intercept $-2$.
- For $y = 2x - 4$, the line has slope 2 and y-intercept $-4$.
4. **Find the intersection point of the two lines:**
Set $x - 2 = 2x - 4$ to find where the lines meet.
$$x - 2 = 2x - 4$$
$$-2 + 4 = 2x - x$$
$$2 = x$$
Substitute $x=2$ into $y = x - 2$:
$$y = 2 - 2 = 0$$
So, the lines intersect at the point $(2, 0)$.
5. **Determine the region satisfying both inequalities:**
- The region is the set of points $y$ such that $2x - 4 \leq y \leq x - 2$.
- This region lies between the two lines, including the lines themselves.
6. **Summary:**
- The graph is the shaded region between the lines $y = 2x - 4$ and $y = x - 2$, including the boundary lines.
**Final answer:** The graph of the relation $R$ is the region bounded by and including the lines $y = x - 2$ and $y = 2x - 4$, with the intersection point at $(2,0)$.
