  • Perpendicular lines from equation - Khan Academy
    A perpendicular line will intersect it, but it won't just be any intersection, it will intersect at right angles So these two lines are perpendicular Now, if two lines are perpendicular, if the slope of this orange line is m-- so let's say its equation is y is equal to mx plus, let's say it's b 1, so it's some y-intercept-- then the equation
  • Perpendicular lines from equation - Khan Academy
    For perpendicular lines, the slopes must be opposite reciprocals (different signs and fraction inverted) So -3 and 1 3 or 2 3 and -3 2 are pairs of perpendicular slopes
