x=3-3y in slope intercept form

Is it y=-1/3x+1

I don't think so.

To answer the question, we need to rewrite the equation x = 3 - 3y in slope-intercept form, which is y = mx + b, where m represents the slope and b represents the y-intercept.

Start by isolating y on one side of the equation:
x = 3 - 3y

Add 3y to both sides:
3y = 3 - x

Divide both sides by 3:
y = (3 - x)/3

To simplify further, rewrite (3 - x) as (-x + 3):
y = (-x + 3)/3

This equation can be rearranged to have the x-term before the constant term:
y = -x/3 + 3/3

Simplify 3/3:
y = -x/3 + 1

So, the equation x = 3 - 3y can be written in slope-intercept form as y = -x/3 + 1.
