I have only 2 questions PLEASE help. Then I will be all done! THANK YOU!?
1. The coordinates of an ordered pair have opposite signs. In which quadrant(s) must the ordered pair lie? Explain.
2. Will the graph of y = |x| ever have points in Quadrants III and IV? Explain. (clearly plz)
If x is positive and y negative, the point is in quadrant 4.
If x is negative and y positive, the point is in quadrant 2.
Those are the only two possibilities.
|x| is always zero or positive, whatever the sign of x.
y = |x| is therefore confined to quadrants 1 and 2 which are above the x-axis.
It has no points in quadrants 3 or 4.
The point (0, 0) cannot sensibly be assigned to any quadrant, as it is at the junction of all four quadrants.
