For the graph y = -8 find the slope of a line that is perpendicular to it and the slope of a line parallel to it.

Answer 1

x = 2 is perpendicular to y = -8.

x = 2, this slope is undefined.

y = -7 is parallel to y = -8.

The slope is 0, because the line is a horizontal line.

A horizontal line has no slope, 0 slope.

I hope this helps!

Answer 2

y = -8 is a horizontal line and has a slope of 0.

A line perpendicular to y = -8 would be a vertical line and hence, its slope is undefined.

A line parallel to y = -8 would have the same slope of 0.
