harbor seals. Find the equation of the regression line. Then construct a scatter plot of the data and draw the regression line. Then use the regression equation to predict the value of y for each of the given x-values, if meaningful. If the x-value is not meaningful to predict the value of y, explain why not.

(a) xequals=140 cm

(b) xequals=172 cm

(c) xequals=164 cm

(d) xequals=158 cm
