no relationship.





if a relation is represented by a horizontal line, it mainly indicates a constant function i.e. f(x)=c, that means the value of the function remains unchanged with the change of x.
no relationship.





if the line contained a slope it would indicate either a positive or negative correlation. But its its horizontal that means that the variables had little to no effect on each other.
