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

A direct variation is a relationship between two variables that is a constant multiple of the other.
In table 1, x=2 and y=2 in the first row, but then x=6 and y=12 in the next. This means the relationship is not constant and therefor not a direct variation.
In table 2, y/x=7 for each set of variables. That means the relationship is constant and it is a direct variation.
So the answer is B. Table 2.

72 is the mode because it shows up the most number of times
