We have a expression of a line.
We have to re-arrange it and graph it:
[tex]\begin{gathered} 7y-7=-x \\ 7y=-x+7 \\ y=-\frac{1}{7}x+1 \end{gathered}[/tex]The y-intercept is b=1. That tells us that the point (0,1) belongs to the line.
The slope is -1/7.
We could find another point of the line to help graphing.
When y=0, x=7, so the point (7,0) belongs to the line.
We can graph:
