The median-median line for a dataset is y = 1.133x + 0.731 the least-squares regression line for the same dataset is y = 1.068x + 0.731. which regression equation better predicts the y-value for the point (50, 60) ?

The median-median line is a better prediction.

Step-by-step explanation:

Both lines predict a value for x=50 that is less than 60. The median-median line value is closer to 60, so could be considered a better prediction.

step-by-step explanation:
