Answer 2

Given:

y ∝ x

when x is 2, the vale of y is 6.

To find:

Value of y when x = 7.

Formula to be used:

y = kx

Step-by-step explanation:

Step 1 of 2

y is directly proportional to x, so y = kx

the value of constant of proportionality when x = 2 and y = 6 is,

$y=kx\\\\6=2k\\\\k=6/2\\\\k=3$

Step 2 of 2

So, when x =7, the value of y will be:

$y=kx\\\\y=3*7\\\\y=21$

The value of y is 21 when x = 7.

[Your question is incomplete, but most probably your full question was -If y is directly proportional to x and if y=6 when x=2, find the value of y when x=7.]
