Getting a line in slope-intercept form means solving for y and getting everything else to the other side.

With the equation in the form `x=3y-5` , we need to have anything that doesn't look like y to go to the other side.  And, although it doesn't matter which order you do the operations in, it is usually a little easier if you move stuff furthest from y first.

`x=3y-5`   we usually have the y by itself on the left

`3y-5=x`    add 5 to both sides

`3y=x+5`   now divide both sides by 3

`y=1/3 x + 5/3`    we are done!  

This means the slope is `m=1/3` and the y-intercept is `b=5/3` .

The slope-intercept form of the line is `y=1/3x+5/3` .

You should remember that slope intercept form of equation of a line is `y = -(B/A)x - (C/A) => y = mx + n` .

`m = -B/A`  (slope of line)

`n = -C/A`  (y intercept)

Comparing the given form to the slope intercept form yields that you need to isolate the term that contains y to the left side such that:

`3y = x + 5`

You need to divide by 3 both sides such that:

`y = (1/3)x + 5/3`

Hence, putting the given equation in the slope intercept form yields `y = (1/3)x + 5/3` .
