What Parallel and perpendicular gradients means in Mathematics A-Level, as defined for Pearson Edexcel.
Definition of Parallel and perpendicular gradients
Check what you remember
Read the wording for your board, then hide it and explain Parallel and perpendicular gradients in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: Pearson Edexcel
Two lines are parallel when their gradients are equal, m₁ = m₂, and perpendicular when m₁m₂ = −1, so a perpendicular gradient is the negative reciprocal.
