x-intercept is when y=0. I am assuming this is the line where one wants the x-intercept. If not, I need a point in order to find the line perpendicular to this one. The slope is not enough.
The equation then become -3=3(x+1) for the given line.
-3=3x+3
-6=3x
x=-2
(-2,0)

This one is perpendicular,y-3=-%281%2F3%29%28x%2B1%29, but not yet what you want.

y-3=-x%2F3-1%2F3
-3y%2B9=x%2B1
-3y=x%2B1-9
3y=-x%2B8
y=-x%2F3%2B8%2F3

But the y intercept will be different .... What point do you want this line to pass through? Your question description is not complete, but you have something y=-x%2F3%2Bb. When you know what point is to be included, you can solve for b.
