Answer 1

Question 1

b. (0, 1)

Question 2.

d. (3, -7)

Step-by-step explanation:

Question 1.

We are asked to find the coordinates of point D after we have reflected it about the vertical axis x = 2.

Reflecting D(4, 1) about the x = 2 line has the following effect.

Therefore, the coordinates of Rx=2(D) are (0, 1) which is choice b.

Question 2.

Rotating (-3, 7) 180 degrees counterclockwise lands us at

As a general rule, 180 rotation does the following transformation

`(x,y)\rightarrow(-x,-y)`
