Question

Find the constant of proportionality for the table of values and write in the form y = kx

A) y = 1/4x

B) y = 4x

C) y = 6x

D) y = 24x

Answer 1

The correct answer is B) y = 4x

Answer 2

Option 'B' is correct.

Explanation:

Since we have given that

Number of lemons used is denoted by 'y'.

Number of glasses of lemonade is denoted by 'x'.

As we can observe that ,

`(6)/(24) = (8)/(32) = (7)/(28) = (2)/(8) = (4)/(16) = (1)/(4) \\`

so we can write i as

`(x)/(y) = (1)/(4)`

By cross multiplication

y=4x

So, if write it in the form y=kx,

It will be y=4x.
