Question

Can you write a linear inequality whose solution contains only points with positive x-values and y-values? why or why not?

Answer 1

No, you can not. So a linear inequality would be an infinitely long straight line on a math graph. Having a solution contains only positive x, y value would mean that your line cannot exceed the first quadrant of the graph. Try to draw an infinite long straight line, only within the first quadrant, clearly, you can not.
