x = y -6
I think it's 6.216 x 10^8 if this is about standard notation
Given:
y is proportional to x.
y=10 and x=8.
To find:
The constant of proportionality and the equation for the proportional relationship.
Solution:
y is proportional to x.

...(i)
Where, k is the constant of proportionality.
Putting y=10 and x=8, we get



Putting
in (i), we get

Therefore, the contestant of proportionality is
and the equation for the proportional relationship is
.
