   27 lis 2016 · If we wish to have perpendicular lines, we may turn this pair of lines into position. Say we want one of the gradients to be $a/b$. We can take the $x$ axis and rotate it counterclockwise so it passes through $(b,a)$.

   Definition: Lines that intersect at a right angle (90 degrees). Gradient Relationship: The gradients of perpendicular lines are negative reciprocals of each other, denoted as m 1 × m 2 = − 1 m_1 \times m_2 = -1 m1 ×m2 =−1. The gradient at any point on a curve corresponds to the gradient of the tangent at that point.

   Perpendicular Lines (HIGHER TIER) Two lines are perpendicular if one is at right angles to another- in other words, if the two lines cross and the angle between the lines is 90 degrees. If two lines are perpendicular, then their gradients will multiply together to give -1. Example. Find the equation of a line perpendicular to y = 3 - 5x.
