Question

What is the correlation between the x and y variables? y increases as x decrease y is constant y decreases as x increases y increases as x increases

Answer 1

when the value of x increases, the value of y remains the same

implies that the graph is a horizontal line and the value of y remains unchanged.

this is valid from the graph point of view.

but it really depends on the value of x.

y = x implies an equal increase or decrease of both variables.
