Explanation:
#"the vertex and focus lie on the axis of symmetry"#
#"the coordinates both have the same x-coordinate"#
#"indicating the axis of symmetry to be"#
#x=6#
#"the distance from the vertex to the focus and directrix"#
#"is equal but on opposite sides of the vertex"#
#rArrd=3-2=1#
#"hence equation of directrix is"#
#y=1#
