Question

The point M 6,-4 is reflected over the y-axis. what are the cordnates of the resulting point, M?

Answer 1

A reflection over the Y-axis is given by:

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

Substitute for (x,y)=(6,-4):

`(6,-4)\rightarrow(-6,-4)`

Therefore, the new coordinates of the point after a reflection over the Y-axis, are:

`(-6,-4)`
