Answer:
[tex]y=-x+3[/tex]
Step-by-step explanation:
Y=mx+b is slope intercept form
m=slope
b = y intercept
we use rise over run to find the slope -3/3=-1
So -1 is the slope
And we see that the line intersect with the y axis at 3 so that is the y intercept so we fill in what we know into the equation
[tex]y=-x+3[/tex]
I hope this helps
