#4i# is represented by the point #(0,4)# on the complex plane

Explanation:

Complex nmbers consist of Real part and an Imaginary part in the form: #z= (a + bi)# #{a,b} in RR#

The complex plane is simply an #xy# plane where the #x#-axis represents the Real coordinate (#a#) and the #y#-axis represents the Imaginary coordinate (#b#).

In this example: #z=4i -> a=0# and #b=4#

Therefore #4i# is represented on the complex plane by the point #(0,4)#
