Yes I can confirm "a" is the right answer. Y is represented by the perpendicular line and X by the horizontal line.
The intersection on both coordinates is O (zero).
On the X coordinate all the square on the right of zero are poziti (ex: 5 or +5). On the left side are the negative or minus numbers.
The same applies to the Y coordinate: above zero is positive , undet zero is negative.
Therefore you just have to count the squared starting from the intersection (zero): hom many on the right(positive), left(negative), up(positive) and down(negative).
So we have:
On X axis
right: +5
Left: -4
On Y axis
Up:+3
Down: -2.
The answer is "a".
