In the frame on the right, an estimate is made of the true slope and intercept for each repeated random sample. It is well-known that the covariance between intercept and slope estimates is negative. In this frame, you can observe this well-known relationship by observing the general motion of the "blue dot" as you vary the sample size and repeated random samples.
