We have been given a graph that involves Real axis and Imaginary axis.
From that graph we have to choose correct line segment which joins complex numbers 2+2i and -1+3i.
We know that if complex number is (a+bi) then real part "a" is always plotted along x-axis and the imaginary part "b" is always plotted along y-axis just like point (a,b) on x-y graph.
So 2+2i means point (2,2) on x-y graph which is at point B.
similarly -1+3i means point (-1,3) which will be at point A.
So the line segment joining them will be AB
Hence final answer is the line segment AB.
Answer:

The numbers of pears and apples bought are 16 and 20 respectively
let
x = number of pears
y = number of apples
He bought 4 more apples than pears. Therefore,
He bought a number of pears and apples and paid $128 for them. Therefore,
<h3>System of equation:</h3>
y - x = 4
4y + 3x = 128
Therefore,
3y - 3x = 12
4y + 3x = 128
7y = 140
y = 140 / 7
y = 20
Therefore,
20 = x + 4
x = 20 - 4
x = 16
