Question 967657: Why the graph y>0 must lies above the x axis? explain clearly pls. Found 2 solutions by Theo, Alan3354:Answer by Theo(13342) (Show Source):
You can put this solution on YOUR website! the line of y = 0 is on the x-axis.
the area above that line satisfies the inequality.
your inequality is y > 0
graph the line of y = 0
find the area on the graph that satisfies the inequality.
that is the area above that line.

-----------------
The y value of any point is its distance from the x-axis.
(x is the distance from the y-axis)
The typical graph of the x-y plane has y increasing in the upward direction.
y > 0 --> the graph is some positive distance from the x-axis --> above it.
