Choice A is the correct answer. The x-axis is the line $y=0$.

1. Above: Greater than ($>$).
2. Strictly: Strict inequality ($>$).
3. Result: $y > 0$

?�� Strategic Tip: The equation of the x-axis is $y=0$. The equation of the y-axis is $x=0$.

Choice B is incorrect because it represents the region right of the y-axis. Choice C is incorrect because it includes the axis (not strictly above). Choice D is incorrect because it represents the region below the x-axis.
