Can i plzz get some with mathh

the line segment is reflected about the y-axis to form a'b'. which statement describes a'b'?

a'b' is half the length of ab.
a'b' and ab are equal in length.
a'b' is greater than twice the length of ab.
a'b' and ab are perpendicular.

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). =
