Maths 3 Mark Question

Draw perpendiculars AP, BP, CQ and DR from A, B, C and D on the x-axis. Also, draw perpendiculars AW, BX, CY and DZ on the y-axis.
From the figure,
we have:
AW = 1 unit and AP= 1 unit.
So, the coordinates of vertex A are (1, 1).
Similarly, BX=1 unit and BP= 4 units
So, the coordinates of vertex B are (1, 4).
CY = 4 units and CQ= 6 units
So, the coordinates of vertex B are (4, 6).
DZ = 5 units and DR= 3 units
So, the coordinates of vertex B are (5, 3).

The examples of points having x-coordinate as zero are (0, 3), (0, 6), (0, 9). This can be represented in the following manner:
From the figure, it can be seen that these points lie on the y-axis. Hence, the statement is true.
