# What is the graph of the inequality in the coordinate plane x ≥ 3?

See below.

#### Explanation:

$x \ge 3$

First consider $x = 3$

This is the vertical line through the point (3, 0) and all other values of $y \in \mathbb{R}$

Hence, $x \ge 3$ is the area consisting of this vertical line and points $\left(x , y\right) : x > 3 \forall y \in \mathbb{R}$

This area is shown graphically by the shaded area below extended to $+ \infty$ for $x$ and $\left(- \infty , + \infty\right)$ for $y$
