Write the coordinates of the points marked on the axes in Fig. 3.12.

Text Solution

Verified by Experts

We can see the given graph that point A is at a distance of 3 units from the Y-axis and at a distance zero units from the X-axis.
Therefore the x-coordinate of A is 3 and y-coordinate is 0.
Hence, the coordinates of A are (3,0).
Similarly,
The coordinates of B are (2,0).
The coordinates of C are (−1,0).
The coordinates of D are (−2.5,0).
The coordinates of E are (−4,0). ...
