An experimenter plots his collected data on a graph and sees that all of the data points fit perfectly onto a horizontal line. What relationship does this represent between the variables?

A Strong, direct

B Strong, inverse

C Weak, direct

D No relationshipRelationships?
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.
