Question

Reflect (4, -6.5) in (a) the x-axis and (b)
the y-axis.

Answer 1

[see below]

Explanation:

Reflection across the x-axis is:
`(x,y)\rightarrow(x,-y)`

Apply that to the point:
`(4,-6.5)\rightarrow(4,6.5)`.

Reflection across the y axis:
`(x,y)\rightarrow(-x,y)`

Apply that to the point:
`(4,-6.5)\rightarrow(-4,-6.5)`

Hope this helps.
