Answer:
Only A, B and C are the points whose coordinates are equal to 7.
Explanation:
Considering the point A
As the location of point A is (0, 7)
The sum of their coordinates is equal to 0 + 7 = 7
Considering the point B
As the location of point B is (2, 5)
The sum of their coordinates is equal to 2 + 5 = 7
Considering the point C
As the location of point C is (6, 1)
The sum of their coordinates is equal to 6 + 1 = 7
Considering the point D
As the location of point D is (4, -3)
The sum of their coordinates is equal to 4 + ( -3 ) = 1
Considering the point E
As the location of point E is (1, -6)
The sum of their coordinates is equal to 1 + ( -6 ) = -5
Considering the point F
As the location of point F is (-2, -4)
The sum of their coordinates is equal to -2 + ( -4 ) = -2 - 4 = -6
Considering the point G
As the location of point F is (-5, -2)
The sum of their coordinates is equal to -5 + ( -2 ) = -5 - 2 = -7
Considering the point H
As the location of point H is (-4, 3)
The sum of their coordinates is equal to -4 + ( 3 ) = -4 + 3 = -1
From the above discussion, only A, B and C are the points whose coordinates are equal to 7.
