Which system of linear equations has the same solution as the one shown below? x - 4y= - 10 x + y = 5 1) 5x = 10 x + y = 5 2) -5y = -5 x+y=5 3)-3x = - 30 x + y = 5 4)-5y = -5 x - 4y = -10​

Given are five observations for two variables, x and y. xi 1 2 3 4 5 yi 3 7 5 11 14 which of the following is a scatter diagrams accurately represents the data? what does the scatter diagram developed in part (a) indicate about the relationship between the two variables? try to approximate the relationship betwen x and y by drawing a straight line through the data. which of the following is a scatter diagrams accurately represents the data? develop the estimated regression equation by computing the values of b 0 and b 1 using equations (14.6) and (14.7) (to 1 decimal). = + x use the estimated regression equation to predict the value of y when x = 4 (to 1 decimal). =
