7. The point M(x, y) is reflected over the x-axis. Use arrow notation to describe the original point and its
reflection.

(x, y) (–x, –y)
(x, y) (x, –y)

I did not answer your question the first time you posted it, since it looks like an obvious "homework dump"
The first 4 questions simply require that you sub in the values and test.

#5, what happened to the x and to the y value of the original point?
-looks like 4 was added to the x, and 2 subtracted from the y
Now, which of the choices says that ?

#6 , take point j(10,5) . now add 5 to the x and 4 to the y. What do you get?
do that to the other points.

#7
suggestion:
take any point you feel like and plot it.
Now reflect it in the x-axis. What are the new coordinates?
Which choice matches that???

yes

WHAT that was so not helpful?!
