SOLUTION: When graphing the inequality 3x-2y≥ 0, why can’t we use (0, 0) as a test point/ If we test the point (-4, 2), do we obtain a false statement or true one?
Question 642887: When graphing the inequality 3x-2y≥ 0, why can’t we use (0, 0) as a test point/ If we test the point (-4, 2), do we obtain a false statement or true one? Answer by MathLover1(20850) (Show Source): You can put this solution on YOUR website! you are given:
}
that inequality simplifies to:
....=>...=>...
The of the inequality is
The point (,) is the boundary line. It the
equality but be used to test the inequality it is the .
You have to use a test point that is on the .
Using (, ) you get ...=>.....=>...
=>...
That is so the half-plane does containing (, ) is the solution set for the inequality.
