Question

The point (–6, –3) is reflected across the x-axis. What are the coordinates of the image point?



(6, –3)


(6, 3)

(–6, 3)


(–3, –6)

Answer 1

when you reflect across the x axis you can see that th epoint moves to the same distance from the horizontal line, but on the other side -

So you can see that the Y value becomes -Y (minus Y) when it is reflected
The X value does not change

so
what is the Y value of the original point in your question?
what is -Y in your question?
