Answer:

The value of y for x = 8 is 60  .

Step-by-step explanation:

Given expression as :

For x = 2  , y = 15

Let the equation be written with constant k'

So, y = k x

Or, k = [tex]\dfrac{y}{x}[/tex]

∴   k =  [tex]\dfrac{15}{2}[/tex]

Now, again

For x = 8

equation can be written as

   y = k x

Or,  y =  [tex]\dfrac{15}{2}[/tex] × 8

Or,  y = [tex]\frac{15\times 8}{2}[/tex]

∴    y = 15 × 4

I.e  y = 60

Hence The value of y for x = 8 is 60  . Answer
