Final answer:
To find the coordinates of the second point, we add the vertical distance of 6 units to the y-coordinate of point P (8, -4), resulting in the coordinates (8, 2).
Step-by-step explanation:
The student is asked to find the coordinates of a point that is 6 units above point P, which has coordinates (8, -4) on a grid where each square is 2 units in length. Since the question specifies the second coordinate is 'above' point P, we are only dealing with vertical movement on the y-axis, which means the x-coordinate will remain the same. Therefore, to find the second coordinate, we add the vertical distance to the y-coordinate of point P. Each square in the grid represents 2 units, so 6 units correspond to 3 squares. Adding this value to the y-coordinate of P, we get -4 + 6 = 2. Thus, the second coordinate is (8, 2).
