**[SOLVED] Another simple question that I don't get :(**

## Homework Statement

Find the Length of the indicated curve

y=2x-3 x[1-3]

## Homework Equations

Arc Length=[tex]\int[/tex][tex]\sqrt{1+[f'(x)]^{2}dx}[/tex]

## The Attempt at a Solution

ok so y'=2 of course,

so it becomes a problem of [tex]\int from 1 to 3 for \sqrt{5}[/tex]

using substitution, u=5 ,and this is where i get a little confused...

du=0dx which would make dx=du/0

the answer becomes 2[tex]\sqrt{5}[/tex]

I'm sure I'm making it harder than it is, I always do... :(
