is the symmetric point of point A (−2,−6) about the angle bisector of the Quadrant II and IV, and point Q is the symmetric point of point A symmetric about the point (5,2). (1) What are the coordinates of point P and Q?
In the xy-coordinate plane, (LM) passes through the origin. If (LM) is perpendicular to (RS) and the two lines intersect at point (5, 3), what are the coordinates of the point at which (RS) crosses the x-axis? () A. (0,6) B. ( 0,(34)3) C. ( (34)5,0) D. (10,...
The coordinate plane is a plane determined by two perpendicular lines, the x-axis and the y-axis. The x-axis is the horizontal axis, and the y-axis is the vertical axis. Every point in the plane can be stated by a pair of coordinates that express the location of the point in terms...
