Hi all,


equation is y=0.78x + 1.52


"this equation should more appropriately be written as ln y = mx + c"
(ln is natural logarithm)


"write your equation with ln y as the subject then (using exponential laws) rearrange to make y the subject and express in the form y=ae^(cx)"

Why?

It feels as though you've dropped us in at the end of a conversation. But I'm pretty sure we'll need at least some of that conversation, in order to know what's going on.

"write your equation with ln y as the subject then (using exponential laws) rearrange to make y the subject and express in the form y=ae^(cx)"

So which is it? Should the equation be of the form "y = ae^(cx)", or of the form "ln(y) = mx + c"?
