Find the equation to the straight line passing throu(a) the origin and

1.	Find the equation to the straight line passing throu(a) the origin and perpendicular tox+2y-4(b) the point (4, 3) and parallel to 3x+4y 12(c) the point (4, 5) and (i) parallel to.(ii) perpendicular to 3x-2y + 5 = 0.
Answer» a) y = 2xb) 3x + 4y = 24c) (i) 3x - 2y -2 = 0 (ii) 2x + 3y -23 = 0 this is only in example can u explain me how this answer came

Answer»

a) y = 2xb) 3x + 4y = 24c) (i) 3x - 2y -2 = 0 (ii) 2x + 3y -23 = 0

this is only in example

can u explain me how this answer came
