Linear equation given as traverse You need to find - Coefficient of a straight line perpendicular - Coefficient of b  straight line perpedicular Coefficient a We are looking for the inverse of the number of opposite sign a₁ = - 1/4  ⇔ a₂ = 4 substantiation a₁ *a₂ = -1 - 1/4 * a₂ = -1 a₂ = -1 * (- 4) to the model equations we put all the known values a₂ = 4    P=(-4,3)                     x,y y = ax + b 3 = 4*(-4) + b    we can calculate b , because it is the only unknown 3 = -16 + b b = 3 + 16 = 19 simple perpendicular y = 4x + 19
