We have a figure that has to be rotated 90° counterclockwise.
We can deduce the rule by graphing:
Then, we can write the rule as:
[tex]P=(x,y)\longrightarrow P^{\prime}=(-y,x)[/tex]
The large dot has coordinates (1, 5),
Then, if we apply the rule, we will get:
[tex]P=(1,5)\longrightarrow P^{\prime}=(-5,1)[/tex]
Answer:
Point in original figure: (1, 5)
Point in final figure: (-5, 1)
