Asked by lilman

The vertices of a triangle are P(-8,1), Q(-6,-8), and R(4,-3) Name the vertices of the image reflected across the x-axis.
my answer;
P1(-8,1), Q1(-6,8), and R1(4,3)
Answered by MathMate
All good except P1.
Can you spot the error?
Answered by lilman
The only choices they give are;
P1(-8,1),Q1(-6,-8),R1(4,-3)
P1(-8,-1),Q1(-6,8),R1(4,-3)
P1(8,1),Q1(6,-8),R1(-4,-3)
P1(8,-1),Q1(6,8),R1(-4,3)
Soo I don't understand
Answered by MathMate
Your answer does not correspond to any of the choices, neither does mine!

So there is probably is mistake in posting the question.

Once you start using the correct question, think of the following.

There is a general misconception about multiple choices in mathematics.
The safest way to use the multiple choices is NOT to look at the answers. Try to do the calculations yourself, figure out the answer, THEN check which answer corresponds to yours. In a way, you use the choices to check your answer.

Here we are talking about reflection about the x-axis. What does that mean to you in terms of transformations?
You have probably learned that reflection about the x-axis is the transformation:
T(x,y) -> (x,-y)
Apply the transformation to each of the three points and then look for the correct choice. You can't miss it.

I think I got it P1(-1,-1), Q1(-6,-8),R1(4,3)
Thank you!

I do not believe that the 4 given choices correspond to the question.
Either there is a typo in the question, or the answer.
