if you could give all coordinates that make the line in answer it would be much appreciated.

Given:
The slope of the line is m = -1 and passes through the point (5,-1).
Explanation:
The general equation of the line passing through points (x_1,y_1) and has slope m is,
[tex]y-y_1=m(x-x_1)[/tex]Determine the equation of the line.
[tex]\begin{gathered} y-(-1)=-1(x-5) \\ y=-1(x-5)-1 \\ =-x+5-1 \\ =-x+4 \end{gathered}[/tex]Plot the equation of the line.
