Question

(-7,8)(-9,10)(-6,11) reflected over x-axis What are the new coordinates

Answer 1

When you reflect something over the x-axis, you flip the y-coordinate's symbol but not the x-coordinate's.

So
(-7,8) is now (-7, -8)
(-9,10) is now (-9, -10)
(-6,11) is now (-6, -11)

Hope this helps!

Answer 2

ok so if it is reflected over the x axis is y=-x  so now you can convert it to the x axis terms
