Find the slope of the line that is a) parallel and b) perpendicular to the given line.
1.x=-8
= 1/2x ; 3/7y
2.y=10
=2/3x ; 2/5y
1. If your equation is x = -8, then we have a vertical line and the slope is undefined
I have no idea what is meant by
= 1/2x ; 1/7y
2. for y = 10 , you have a horizontal line with slope of zero
Again, no idea what the rest of the stuff is
