Using the following image, find the slope of the line.

-3

Step-by-step explanation:

To find slope you first need to pick to points where the line crosses a corner.

Slope=

I'm using the points (0,-2) and (-1,1). You can either count up and over for the slope or use the slope equation

y2=second y point

y1=first y point

x2=second x point

x1=first x point

  Now you just solve

or -3

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
