In Fig. 3.2, the point identified by the coordinates (–5, 3) is
a. T
b. R
c. L
d. S

Solution:

In the point (-5, 3), the x coordinate is negative and the y coordinate is positive

So the point lies in the II quadrant

From the figure we observe that the distance of L from the X axis is 5 and from the Y axis is 3

Therefore, the point identified by the coordinates (–5, 3) is L.

✦ Try This: Point (2, 0) lies a. on the positive direction of the x-axis, b. on the negative direction of the y-axis, c. in the third quadrant, d. in the fourth quadrant

We know that

Abscissa and ordinate are used to represent the position of a point on a graph

Abscissa is the coordinate of the x-axis

It is the distance from y-axis measured parallel to x-axis

In the point (2, 0) the abscissa is positive

So it lies on the positive side of the x-axis.

Therefore, the point lies on the positive direction of the x-axis.
