Which reflection(s) reflect a point (-a, a) onto (a, a)?
Select all that apply.
reflection in the y-axis
reflection in the x-axis
reflection in the line y=x and then

reflection in the y-axis

Step-by-step explanation:

Point (-a, a) means:

go a units left and a units up

Falls in 2nd quadrant

Point (a,a) means:

go a units right and a units up

Falls in 1st quadrant

You will see that they are reflections of each other about the vertical axis. Which is the y-axis.

So, the points are "reflection in the y-axis".

Note: We took a = 2 and plotted (-2,2) and (2,2) in the image attached to show the reflection.

can you add an image ?
