Identify the variation as direct, inverse, joint or combined. y = 7x

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

Feel free to ask for more if it´s necessary or if you did not understand something.

step-by-step explanation: examine the two-step equation.
