Answer:
None of then, the slope is 1
Step-by-step explanation:
We have to use the general equation for lines, that is:
[tex]y=mx+b[/tex]
where 'm' is the slope (by comparison)
So, we only need to compare your equation ([tex]y=x-3[/tex]) with the general one.
We can see that m=1, b=-3
So our slope turns out to be equals to 1
