Point Q is plotted on the coordinate grid. Point P is at (20, −30). Point R is vertically above point Q. It is at the same distance from point Q as point P is from point Q. Which of these shows the coordinates of point R and its distance from point Q? A. Point R is at (−40, 30), a distance of 60 units from point Q
B. Point R is at (−40, −10), a distance of 20 units from point Q
C. Point R is at (−40, −30), a distance of 60 units from point Q
D. Point R is at (−40, 10), a distance of 20 units from point Q
