What is the equation of a line that has a slope of -2 and goes through (-1, -1)?

a) y + 1 = -2(x + 1)

b) y - 1 = -2(x-1)

c) y + 1 = 2(x + 1)

d) y - 1 = 2(x - 1)

answer: c i think

step-by-step explanation:

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
