Question

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.

Answer 1

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

Answer 2

(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
