Question

Choose the correct option:

The coordinates of a point P in a system are (5, 8). The coordinates of the same point in the system are ____________.

A. (−8, 5)

B. (8, 5)

C. (8, −5)

D. (−8, −5)

Solution

We mark the point (5, 8) in the coordinate systemas shown below.

Now, if we change the coordinate systeminto , the location of the point (5, 8) changes as:

On observing the graph, we observe that the coordinates of the point are (8, −5).

Correct Option: C
