Point Q is plotted on the coordinate grid. Point P is at (50, −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? (1 point) On a coordinate grid from negative 50 to positive 50 in increments of 10, Point Q is plotted at the ordered pair negative 20, negative 30. Group of answer choices Point R is at (−20, −10), a distance of 20 units from point Q Point R is at (−20, −40), a distance of 70 units from point Q Point R is at (−20, 10), a distance of 20 units from point Q Point R is at (−20, 40), a distance of 70 units from point Q
