Can someone please tell me how to do this ):

Look at Description

Step-by-step explanation:

Start at the point (0,-4) because the equation has -4 at the end. Then take the slope which is 1/4 you're gonna count up 1 then right 4. the next point will be (-3,4) and so on

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
