Q.Draw the graphical solution of $x\ge 2$ in the coordinate plane.

In two variables, $x\ge2$ is a vertical-line boundary; shade to its right.

Boundary $x=2$ is vertical; $\ge$ makes it solid. Test $(0,0)$: $0\ge2$ false, so shade the side away from the origin (right).

In the coordinate plane, the equation $x=2$ (with $y$ free) is the vertical line through $(2,0)$ parallel to the $y$-axis.

Solid or dashed: the sign is $\ge$ (weak), so the line $x=2$ is solid and included.

Which side: every point with first coordinate greater than $2$ satisfies $x\ge2$, so the solution is the region to the right of the line. Testing the origin confirms it: $x=0$ gives $0\ge2$, false, so the origin's side (the left) is not the solution — shade the opposite side, the right.

Check (independent verification): $(3,5)$ has $x=3\ge2$ ✓ inside; $(2,-1)$ has $x=2\ge2$ ✓ on the included line; $(1,0)$ has $x=1\ge2$ false ✓ outside.

Treating $x\ge2$ as a single point or a segment on the $x$-axis. In the plane it is a whole vertical half-plane, because $y$ can be any real number.
