Answer:

Slope is undefined and there is no y-intercept.

Explanation:

#x=4# represents a vertical line passing through #x=4#.

1] It is not possible to define its slope #m#;
in fact #m=(Deltay)/(Deltax)# but #Deltax=4-4=0# so you get a division by zero!
2] Being a vertical line through #x=4# it will never cross the #y# axis!
