Question

Point Q is plotted on the coordinate grid. Point P is at (50, −40). 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?

Answer 1

(-40 30)

Explanation:

Point R is at (−40, 30), a distance of 60 units from point Q

Answer 2

Point P is at (50, −40). Point R is vertically above point Q. It is at the same distance from point Q as point P is from point Q.

Point P is the same distance from Point Q as Point R.

Point R is at (-30, 40), 80 units from Point Q.
