Question

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+b 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+b is given by Root a^2+b^2 . Which of the complex numbers z1, z2, z3, z4, z5 below has the greatest modulus ? ​

Answer 1

Explanation:

You are correct. For every point, draw a line from the origin. The z1 point and origin has the biggest line, this has the greatest modulus.
