Use a geometric representation to determine the difference of the complex numbers. Z1 = -2- 61
Z2 = 5 + 91
Z=-7 +15 /
z = 7 - 151
Z=-7 - 151
z = 7+ 157

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
