Answer:
[tex]y = -x + 3[/tex]
Step-by-step explanation:
The equation for a line is: y=mx+b, where m is the slope, and b is the y-intercept.
You are given the slope, x, and y. Simply plug it into the equation above to find b.
[tex]0=-1(3)+b[/tex]
[tex]0 = -3+b[/tex]
[tex]3=b[/tex]
Now that you have b, plug in both m and b into the original equation.
[tex]y=-x+3[/tex]
