I know where two lines intersect is the solution for a set of linear equations. But for linear inequalities how do you find the solution????

Best ResponseYou've already chosen the best response.2start by writing both inequalities in the form y = ________ if y < _____, shade below the line if y > _____, shade above the line the solution will be the area where the shaded parts overlap (unlike linear equations, the solution isn't going to be just one point. it will be a region of points)

Best ResponseYou've already chosen the best response.2also, for < and >, use a dotted line. for <= and >=, (greater than or equal to/less than or equal to) use a solid line

Best ResponseYou've already chosen the best response.2since this is a greater than symbol, I shade everything above this line

Best ResponseYou've already chosen the best response.2so, if it asks for a solution, you can pick any point that falls within that shaded area up there

Best ResponseYou've already chosen the best response.2I think (1,5) falls within the shaded region, so that's one possible solution

Best ResponseYou've already chosen the best response.2does that make things a bit more clear?

Best ResponseYou've already chosen the best response.0how would you write the solution out tho

Vocaloid

Best ResponseYou've already chosen the best response.2you can't, there are an infinite number of solutions

Best ResponseYou've already chosen the best response.2the best you can do is show them the graph and list out a few possible solutions

Best ResponseYou've already chosen the best response.1If you have a closed solution region, and you're only recording points with integer coordinates, then it is possible to list all of the solutions. Other than that, there would be infinitely many solutions and it is best to use a graph to show the solution set.

Best ResponseYou've already chosen the best response.1In your case, the solution region isn't closed because it continues on forever in this direction dw:1444609982769:dw
