A parabola has an equation of y2 = 8x. Find the equation of the diameter of the parabola, which bisect chords parallel to the line x – y = 4.

Answer»

As diameter of PARABOLA is chords bisection all PARALLEL chards of the parabola. And the equation is y =a/2m. Here SLOPE of chard to be bisected is 1 so EQN REQUIRED will be y =a/2 i.e. y= 1
