Chapter 14, Problem 9CT

To determine

Tofind: the coordinates of the points after transformation $H_O\circ R_x$ .

Answer to Problem 9CT

The coordinates after transformation are $P\text{'}\left(-4,2\right)\text{ and }Q\text{'}\left(-1,2\right)$ .

Explanation of Solution

Given information:

From the figure provided in the question, it can be observed that

The coordinates of points are $P\left(4,2\right),Q\left(1,2\right)$ .

Calculation: to find the coordinates after transformation $H_O\circ R_x$ , change $x$ coordinates sign and $y$ coordinates remain same,

Thus, the coordinates of points after transformation are $P\text{'}\left(-4,2\right)\text{ and }Q\text{'}\left(-1,2\right)$ .
