Which of the points listed is the same distance from the x-axis as the point (7, 8.75)?

The complete question in the attached figure

we know that

The distance of the point (7, 8.75) to the x-axis (the horizontal line) is 8.75

then
 case A) (-7, 5.25)---------> is not correct ( the distance to the x-axis is 5.25)
 case B) (8.75, 6)---------> is not correct ( the distance to the x-axis is 6)
 case C) (6, -8.75)---------> is correct ( the distance to the x-axis is 8.75)

the answer is the option C) (6, -8.75)

It will never be positive always negative
