Question

Triangle LMN is reflected over the x-axis to form triangle L'M'N'. What are the coordinates of point N'?

Answer 1

The general rule for a reflection over the x-axis is:

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

Coordinates of point N are:

$(-5,4)$

Then, point N' has coordinates:

$(-5,4)\rightarrow(-5,-4)$Answer: (-5, -4)
