The position of the least-squares regression line is defined by two elements:
A)the X intercept and the slope of the line.
B)the X intercept and the Y intercept.
C)the Y intercept and the slope of the line.
D)the intersection point of the X and Y axes and the slope of the line.

The Y intercept and the slope of the line determine the position of the least-squares regression line. The Y intercept is the point where the line intersects the Y axis, and the slope determines the steepness and direction of the line. The X intercept and the intersection point of the X and Y axes are not relevant in determining the position of the least-squares regression line.
