When we graph the inequality 4x-2y ≥0, why can’t we just use (0,0) as a test point? If we test the point (6, -5), do we obtain a false statement or a true one?

    because (0,0) lies on the line that you are trying to test and therefore would give you no information to determine which side of the line is true

    to test the point (6,-5) just substitute the values into 4x-2y 4(6)-2(-5)≥0 and determine whether this is true or false

    solve it first, and then determine whether the answer is greater than 0 if it is, then it is true if it is not, then it is false
