What is the slope of a line that is perpendicular to a slope of 0/7? Algebra Forms of Linear Equations Equations of Perpendicular Lines 1 Answer smendyka Feb 26, 2017 Because a slope of #0/7# is #0# this is the slope of a horizontal line. The line perpendicular to this would be a vertical line. A vertical line, by definition, has an undefined slope.
