 Question 340273: What is the graph for xy>=0; how would I solve for y in this case? and the graph for y^2>x^2?Answer by Fombitz(13828)   (Show Source): You can put this solution on YOUR website!Think about it. First quadrant, , , Second quadrant, ,, Third quadrant, , , Fourth quadrant, , , Also include the in the first and third quadrant and on the x and y axes. . . . Solve for and That's two lines. . . . Pick points in each region and test the inequality. Since the "=" sign is not included the regions are broken up into 8 regions not just 4 regions, so use the two lines and the two axes to demarcate each region. In the first region, , False, this region is not in the solution region. . . . In the second region, , True, this region is part of the solution region. . . . Continue until you've tested a point in each region. Remember the and axes are not included in the solution region.
