Find the combined equation of the lines passing through the origin and having inclinations π 3 and 5 π 3 . Find the joint equation of the lines 3x – 2y + 5 = 0 and 5x – 3y = 0. Share with your friends Share 1 Ayushi Chaurasiya answered this Dear Student, eq. of line is y =mx +c .If line is passing from 0 then value of c =0.So eq. of line will be y = mx.m is slope which is also equal to tan θ .⇒ y = (tan θ) x (where tan θ = slope) 0 View Full Answer
