Point l has coordinates (3 -5). the coordinates of point l' after a reflection are (-3,-5). without graphing, tell which axis point l was. reflected across. explain your answer.

(x,y)
when x turns negative, it was reflected across the y axis
when y turns negative, it was reflected across the x axis

(3,-5) to (-3,-5)
x turned negative
it was reflected across the y axis

If the x coordinate changes, then it is reflected over the y axis.

I’m confused what’s happening
