Question

The rule r_y-axis ° R_0,90 (x,y) is applied to ABC. Which triangle shows the final image?

a. 1
b. 2
c. 3
d. 4​

Answer 1

Answer: 4

Explanation:

Simply rotate the graph 1-turn to the left to see where the triangle lands. The x-axis will be the horizontal line and the y-axis will be the vertical line.

The attachment shows the graph rotated 1-turn to the left (90°).

Notice it is in the exact same position as #4.
