Question

Write the abscissa and ordinate of the following points:
[i] (6,3)
[ii] (-1,-3)
[iii] (-4,0)
[iv] (0,8)
[v] (3,-2)

Answer 1

Hint: Recall the definition of abscissa of a point and the ordinate of a point. Using definition determine the abscissa and ordinate of each of these points.

Complete step-by-step solution -

Abscissa of a point is the x-coordinate of the point. Hence it is the distance of the point from the y-axis.
Ordinate of a point is the y-coordinate of the point. Hence it is the distance of the point from the x-axis.
Hence for point (6,3), we have
Abscissa = 6
Ordinate = 3
For the point (-1,-3), we have
Abscissa = -1
Ordinate = -3
For the point (-4,0), we have
Abscissa = -4
Ordinate =0
For the point (0,8)
Abscissa = 0
Ordinate = 8
For the point (3,-2)
Abscissa = 3
Ordinate = -2.

Note: [1] Students often get confused over whether abscissa is x-coordinate or y-coordinate. We can remember the following trick.
In English alphabet x comes before y.
Hence $x < y$
Also a comes before o.
Hence $a < o$
Hence we have a = abscissa corresponds to x-coordinate and o = ordinate corresponds to y-coordinate.
