Question

does the relationship in this table represent a proportional relationship?

x	0.2	0.4	0.75	0.875
y	0.4	0.8	1.5	1.75

select from the drop - down menu to correctly complete the statement.

the relationship choose... represent a proportional relationship.

Explanation:

Step1: Calculate $\frac{y}{x}$ for first pair

$\frac{0.4}{0.2} = 2$

Step2: Calculate $\frac{y}{x}$ for second pair

$\frac{0.8}{0.4} = 2$

Step3: Calculate $\frac{y}{x}$ for third pair

$\frac{1.5}{0.75} = 2$

Step4: Calculate $\frac{y}{x}$ for fourth pair

$\frac{1.75}{0.875} = 2$

Step5: Check for constant ratio

All $\frac{y}{x}$ equal 2, a constant.

Answer:

The relationship does represent a proportional relationship.
