Answer
Thus, the region includes all the points which are between the horizontal lines $y = 0$ and $y = 4$, and to the left of the vertical line $x = 2$
Note that the points on these three lines are also included in the region.
Work Step by Step
$\{(x,y)\vert~0 \leq y \leq 4 ~and~ x \leq 2 ~\}$
The region includes all the points where $0 \leq y \leq 4$ and $x \leq 2$
Thus, the region includes all the points which are between the horizontal lines $y = 0$ and $y = 4$, and to the left of the vertical line $x = 2$
Note that the points on these three lines are also included in the region.
