Explain this to me : ( ive spent 2 hours trying to understand it and find an answer "identify which table shows a direct variation.

table 1
x y
2 2
6 12
9 18

table 2
x y
2 14
6 42
9 63

a.
table 1

b.
table 2

c.
table 1 and table 2

d.
neither table "

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
