Given the equation of a regression line is y = -2.5x+ 5.3, what is the best predicted value for y given x = 4.9? Assume that the variables x and y have a significant correlation. 

Determine whether the approximate shape of the distribution in the

histogram is symmetric, uniform, skewed left, skewed right, or none of these.
