"perpendicular slope is undefined"perpendicular slope is undefined

Explanation:

"the equation "y=-8the equation y=−8

"is a horizontal line parallel to the x-axis and passing"is a horizontal line parallel to the x-axis and passing
"through all points in the plane with a y-coordinate of "-8through all points in the plane with a y-coordinate of −8

"since it is parallel to the x-axis it's slope "=0since it is parallel to the x-axis it's slope =0

"a line perpendicular to it would therefore be a vertical"a line perpendicular to it would therefore be a vertical
"line parallel to the y-axis"line parallel to the y-axis

"with undefined slope"with undefined slope
