Which of the following could be the value of rOA 0.245OB. 0813O c. 0.921OD. 0.967Given that the regression line has a slope of -0.856 and a y-intercept of -0.013, find the slope-intercept equation of the regression line.Use the regression line to predict the y-value for the x-value of 1.424(Round to three decimal places).

c) we have, ŷ = -0.856x-0.013given, x = 1.424=> ŷ = -0.856*1.424-0.013=> ŷ = -1.232(rounded to…
