how can the relationship between y and x in the form Iny = 3+0.2x, be written in the form y = pq^x.

I tried many ways, but can't find the righ format, someone help please?

1) ln(a)=x means a=exp(x)
2) exp(x+y)=exp(x)*exp(y)

1)lny=3+0.2x => y=exp(3+0.2x). Now you do the 2).

Oh right. Thank you. I got y=exp(3) * exp (0.2x).
That becomes y = exp(3+0.6) * exp(x)
