As shown in the figure, it is known that the straight line L: Y = 2×2 intersects with the X axis and the Y axis at two points A and B respectively (1) to find the coordinates of points A and B; (2) Rotate the straight line L clockwise by 90 degrees around the point B to obtain a straight line L&;, make a straight line L&;, and mark the corresponding point A&; of the point A on the straight line L&;.

(1) When y=0, 2x 2=0, the solution is: x=-1, the coordinate of point A is (-1,0); when x=0, y=2, the coordinate of point B is (0,2). (2) As shown in the figure, the straight line L&; and point A&; are the requirements. (3) …
