In the complex plane, the horizontal axis is called the
real axis and the vertical axis is called the imaginary
axis. The complex number a + bi graphed in the
complex plane is comparable to the point (a,b) graphed
in the standard (x,y) coordinate plane. The modulus of
the complex number a + bi is given by Va² + b².
