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 = 
∴ k = 
<u>Now, again </u>
For x = 8
equation can be written as
y = k x
Or, y =
× 8
Or, y = 
∴ y = 15 × 4
I.e y = 60
Hence The value of y for x = 8 is 60 . Answer
