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 IInd quadrant in the Cartesian plane because for point , x-coordinate is negative and y-coordinate is positive.
Again, the point 
lies in the IVth 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 Ist quadrant as for point , both x and y are positive.
The point lies in the IIIrd 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.
