Point Q is plotted on the coordinate grid. Point P is at (10, −20). 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? Answers:
A. Point R is at (−20, −30), a distance of 10 units from point Q
B. Point R is at (−20, 10), a distance of 30 units from point Q
C. Point R is at (−20, −10), a distance of 30 units from point Q
D. Point R is at (−20, 30), a distance of 10 units from point Q
