#y=1,x=6#

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#
