Question

Which of the following represents a proportional relationship of 1.5 between the x- and y-values? у 5 1 1 2 6 3 7 X y 1 1 1 2 5 3 9 X у 3 2 4 5 6 7 X у 3 2 4 6 6 9

Answer 1

Let us check the table 1

here,

y/x=5/1=5

y/x=6/2=3

y/x=7/3=2.33

In table 1 there is no relationship of 1.5 between the x- and y-values.

Let us check the table 2

y/x=1/1=5

y/x=5/2=2.5

y/x=9/3=3

In table 2 there is no relationship of 1.5 between the x- and y-values.

Let us check the table 3

y/x=3/2=1.5

y/x=5/4=1.25

y/x=7/6=1.166

In table 3 there is no relationship of 1.5 between the x- and y-values.

Let us check the table 4

y/x=3/2=1.5

y/x=6/4=1.5

y/x=9/6=1.5

In table 4 there is relationship of 1.5 between the x- and y-values.

hence, table 4 is the correct answer.
