Hey there!
When we say coordinate pair, we usually express our pair in the form of:
(x, y)
This means the point on the x axis is first, and the point on the y is second in the parenthetical format of coordinates. We know that the x coordinate is the horizontal one, while the y is vertical.
If we start with the x axis, we see that our point, G, is just below the number 2. That means our x coordinate is 2. For the y coordinate, we see that the point is directly lined up with the -3, therefore our y coordinate is -3.
Therefore, our coordinates are (2, -3).
Hope this helps!
