Question

Can someone help me with this question? Thanks! :)

Answer 1

Hi, it's me again.

The y-axis would be the line split vertically down the middle. That said, if you would have to reflect the figure over the y-axis, you would have to think of the line as a mirror. That said, if you're reflecting across the y axis to the from the right to left side, just change the numbers from (x,y) to (-x,y).

(4,6) => (-4,6)
(4,3) => (-4,3)
(6,3) => (-6,3)

Answer 2

Change all the x values to negative the new coordinates are :
(-4,3), (-4,6), (-6,3)
