Answer: No , y does bot varies directly with x.
Step-by-step explanation:
The given table :
x= 5,10,15,20
y=25,25,70,90
As we observe the given data , we conclude that y does bot varies directly with x because one value of y corresponds to two different values of x.
i.e. y=25 corresponds to two x-values x-5 and x=10.
Therefore, y does bot varies directly with x.
Two quantities are said said to be in direct variation , if one quantity increases or decreases with respect to increase of decrease the second quantity (respectively) .
