<h3>Answer: Choice A 
</h3>
The R stands for "rotation". The "O" as a small subscript means "origin" which is where the x and y axis cross. The 90 degrees means we rotate 90 degrees counterclockwise. This is equivalent to 270 degrees clockwise, but writing is not correct as we don't rotate 270 degrees counterclockwise.
Answer:
Step 1:
To find ordered pair solutions, you could create an x and y graph and fill out the x side. Then, plug in an x number to get your y number and graph the ordered pairs to see if they give you a straight line. I'm going to use these numbers: -1, 0, 1, and 2.
Now, let's plug in -1 into the equation first to see what we get for y.
-5 is our y if x was -1.
We do the same for the other three numbers.
Step 2:
With all that done, we can now fill out our table and graph the points.
If you graph these points on graph paper / a graphing website, you will see that these points go in a straight line. If you are given an ordered pair already (for example: (3,5)), then all you have to do is plug in the x into the equation (3) and see if the outcome is true (5).
Since they don't equal each other, then (3,5) is false.
Here is the graph for the table above. I hope I helped you!
