Find the equations of two straight lines which are parallel to the straight line x+7y+2=0 and a unit distance from the point (2,-1).
=========
1) Find the slope of the line.
2) Find the equation of the line perpendicular to the given line thru (2,-1).
3) Find the 2 points 1 unit from (2,-1) on the perpendicular line.
4) Find the 2 equations.
