2 Answers: A and D
Explanation:
The y coordinate can be thought of the height of each point. As long as the height is above ground, then y is greater than 0.
For point A, its height is y = 3.5 and point D has height y = 2.5
It might help to draw horizontal lines from the point until you reach the y axis to determine the height.
Points B and C have negative heights. They can be thought of as locations somewhere underground.
