#### Question 1:

In which quadrant or on which axis do each of the points and lie? Verify your answer by locating them on the Cartesian plane.

#### Answer:

The point lies in the II^{nd }quadrant in the Cartesian plane because for point, *x*-coordinate is negative and *y*-coordinate is positive.

Again, the point lies in the IV^{th} quadrant in the Cartesian plane because for point, *x*-coordinate is positive and *y*-coordinate is negative.

The point lies on negative *x*-axis because for point , the value of *y*-coordinate is zero and the value of *x*-coordinate is negative.

The point lies in the I^{st} quadrant as for point , both *x* and *y* are positive.

The point lies in the III^{rd} quadrant in the Cartesian plane because for point , both *x* and *y* are negative.

#### Question 2:

Plot the point (*x*, *y*) given in the following table on the plane, choosing suitable units of distance on the axis.
