Question

When you reflect across the X-axis,which is a TRUE statement? (again, thinkabout the two coordinate points on thegraph)Both values will switchBoth the X and Y values will changeThe Y value will stay the same, the X valuechangesThe X value will stay the same, the Y valuechanges

Answer 1

Point: (-6, -7)

Relfection across x-axis: (-6, 7)

Graph:

Reflection about the x-axis always changes the sign of the y-coordinate and leaves the x-coordinate unchanged. So as a general rule we have

`(x,y)\rightarrow(x,-y)`

Now in our case

`(-6,-7)\rightarrow(-6,7)`
