The equation of the parabola with its vertex at (1 , 1) and focus (3 , 1) is
(x - 1)2 = 8 (y - 1)
(y - 1)2 = 8 ( x - 3)
(y - 1)2 = 8 (x - 1)
(x - 3)2 = 8 ( y - 1)
The equation of the ellipse whose latus rectum is 8 and eccentricity 1/√2 , is

Are parallel
Intersect on the directrix
Intersect at angle of 45o
Intersect on the tangent at the vertex
