Question

Find the midpoint between (-1+9i) and B=(5-3i)

Answer 1

Answer:

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

$\frac{a+c}{2} + \frac{b+d}{2} i$

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

Midpoint for AB is

$\frac{-1+5}{2} + \frac{9+(-3)}{2}i$

$\frac{4}{2} + \frac{6}{2}i$

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

Answer 2

Answer:

The midpoint between A=(-1+9i) and B=(5-3i) is: (2+3i)

Step-by-step explanation:

A=-1+9i

B=5-3i

Midpoint between A and B: M=(-1+5)/2+[(9+(-3))/2] i

M=(4)/2+[(9-3)/2] i

M=2+[(6)/2] i

M=2+3i
