10.) find the slope of the line.

a.) - 1/3

b.) - 3

c.) 1/3

d.) 3

Step-by-step explanation:

Slope = (y2 - y1)/(x2 - x1)

y2 = 3 , y1 = 1, x2 = 3, x1 = -3

Slope = (3 - 1)/(3 + 3)

Slope = 2/6

Slope = 1/3

unpaid balance is : $149.99-$50 = $99.99 new balance = 149.99+2.62-50 = $102.61 finance charge = 99.99- 0.21/12= $1.75 new balance = 99.99+1.75 = $101.74 average daily balance method average daily balance= 3399.70/30 = $113.32 finance charge = $ 0.21/12ă—113.32 = $1.98 new balance = $149.99-50+1.98 = $101.97

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
