This is an example of a direct variation.

Answer 2

Answer:

Direct variation

Step-by-step explanation:

Hi, to answer the question we haveto analyze the information given.

The expression of y =7x is a direct variation, because if the value of one variable changes, the other variable´s value changes as well.

for example:

if x = 1 , y = 7.

y= 7(1)=7

if x =2 , y= 14.

y = 7(2 ) =14
