The cartesian co-ordinates of the point on the parabola y²=x whose parameter is -4 3 are

Options

  1. A( 4 9 , 4 3 )
  2. B( 4 3 , -4 3 )
  3. C( 4 3 , 4 9 )
  4. D( 4 9 , -2 3 )

Correct answer

D. ( 4 9 , -2 3 )

Step-by-step solution

y²=x t=-4 / 3a= 1 4 (a t², 2 a t )= ( 1 4 16 9 4, -2 3 )= ( 4 9 , -2 3 )
