Equation for perpendicular to the line -7x + 3y = -10j contains the point (-2,-4)

y = 7/3x + 2/3

Step-by-step explanation:

-7x + 3y = -10

3y = 7x - 10

y = 7/3x - 10/3

-4 = 7/3(-2) + b

-4 = -14/3 + b

2/3 = b

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

is there any photos or whatever?
