Question

Pranay only consumes the flavor of juice that shows a proportional relationship with time.

Which flavor shows a proportional relationship?

• A. Flavor 1
• B. Flavor 2
• C. Flavor 3
• D. Can't be determined

Answer 1

The correct option is A Flavor 1

We know that to show a proportional relationship, we have to look for a graph which passes through the origin.


From the graph, we can observe:
For Flavor 1, the equation is $y=x$.
The straight line passes through the origin.

So, Flavor 1 is a preferred choice of juice for Pranay.

Now, for Flavor 2, the equation is $y=x+1$.
The straight line does not pass through the origin.

So, Flavor 2 is not the desired choice for Pranay.

For Flavor 3, the equation is $y=x+2$.
The straight line does not pass through the origin.

So, Flavor 3 is also not the desired choice for Pranay.

$\therefore$ Among the three flavors, Pranay will choose only Flavour 1 as it shows a proportional relationship.
