#### Answer

For the absolute value of $z = 2$, the graph of all the complex numbers $z$ will have their vector vertices lying on the circle $x^2 + y^2 = 2^2$ or on the circle with center at the origin and radius = 2.

#### Work Step by Step

For $z = x + yi$, the absolute value of $z$ is $\sqrt{x^2 + y^2}$.
Now, for the absolute value of $z = 2$, $\sqrt{x^2 + y^2} = 2$ or $x^2 + y^2 = 2^2$ which is a circle with center at the origin and radius = 2.
The graph of all the complex numbers $z$ will have their vector vertices lying on the circle $x^2 + y^2 = 2^2$ or on the circle with center at the origin and radius = 2.
