What is X-3y=9 in slope intercept form and the equation

The slope intercept form would be y = 1/3x - 3

First, you add 3y to each side

That cancels out the - 3y on the left side of the equation and adds a + 3y to the right

Now you have x = 3y + 9

Subtract 9 from each side and now you have

3y = x - 9

Now all you have to do is divide 3 from each side

3y divided by 3 = y

x divided by 3 = x/3 or 1/3 x

-9 divided by 3 = - 3

The end result is y = 1/3x - 3
