What does the scatter diagram developed in part (a) indicate about the relationship between the two variables?There appears to be anegative+ linear relationship between x and y.c. Try to approximate the relationship between x and y by drawing a straight line through the data.Only one straight line can be drawn+ to provide a linear approximation of the relationship between x and y.d.
