Expert Answer:

As the new line is rotated about point B the point B lies on the new line. Also as the line is rotated 90o the new line is perpendicular to the old line. Thus (slope of the new line) = -1/(slope of old line) Find the slope of the old line using the 2 points given and hence find the slope of the new line. The equation of the new line can be found using the slope-point equation of  a line.
