Answer: No, the answer is actually C

Step-by-step explanation: This is because of two simple reflection rules

1) In order to solve this, you first have to reflect point R across the y-axis. There is a rule that must be followed: (x,y) --> (-x,y)

This rule means that whatever was on the x side of the original point is now negative, but the y is left the same.

R(-2,9) --> R'(2,9)

2. The second step is to reflect the second point across the x-axis. Again, there is another simple rule to remember: (x,y) --> (x,-y)

This means that the x of the original point is kept the same, but the y value is now negative. To model this: **REMEMBER TO USE THE POINT FOUND IN STEP 1, SO R'(2,9), NOT R(-2,9)

R'(2,9) --> R''(2,-9)

FINAL ANSWER: C (2,-9)

To solve these problems, you simply need to memorize these rules.
