Plot the following ordered pairs in the same xy-plane. Tell in which quadrant or on what coordinate axis each point lies.

To plot: The given points in the xy-plane and obtain the coordinate axis where each points lies.
Answer to Problem 1PCT
The coordinate axes where the points
Explanation of Solution
In general, any point P in the rectangular coordinate system is represented by the ordered pair
Recall that, x and y are positive in the first quadrant. In the second quadrant, x is negative and y is positive. In the third quadrant, both x and y are negative. And in the fourth quadrant, x is positive and y is negative.
The given points are,
Consider the point
For the point
Similarly, for the point
For the point
In the case of
For the point
Draw the graph and plot the points as shown below in Figure 1.
From Figure 1, it is observed that the dark dots represents the given points
Thus, the coordinate axes where the points
