The statement makes sense.

Work Step by Step

When the complex number $a+ib$ is represented on the complex plain, then $a$ represents the $x$ coordinate and $b$ represents the imaginary $y$ coordinate. Hence, the complex number $a+ib$ can be interpreted geometrically as the point $\left( a,b \right)$ in the $xy$ plane.
