Find the midpoint between a and b, given that a=(-1,+9i) and b=(5-3i)

2 + 3i, midpoint is (2,3)

Step-by-step explanation:

we need to find the midpoint between (-1+9i) and B=(5-3i)

To find the midpoint of two points (a+bi)  and (c+di) in a complex plane,  

we apply formula

A = (-1+9i) and B=(5-3i)

Midpoint for AB is

2 + 3i , so midpoint is (2,3)
