there is a positive correlation between x and y.

The question isn;t clear, but the y-intercept (sometimes called alpha, beta0,) is a constant in the linear model and estimated by the arithmatic mean of all the y values for a given sample.
Thus it tells nothing of the relationship between x and y, so none of the above must be correct.
