To find the coordinates for Z, we first need to find Z.
Z is at the top right of the first quadrant/Quadrant 1 (top right square). To find the coordinates, look for the lines that intersect on Z.
For the X-Axis (Horizontal line, side to side),it is at 9. This means the first half of our coordinates is (9,y), so we can eliminate the second and last answer choices.
For the Y-Axis (Vertical line, straight up and down), Z it located on the 10th line, so the second coordinate for Z is 10.
Our coordinates are (9,10).
Your correct answer is A.), as we are in Quadrant 1.
I hope this helps!
