Question

Triangle XYZ is reflected across the y-axis, and X = (4, –5). What are the coordinates of X’ ?

Answer 1

Explanation:

Anytime a reflection takes place across the y axis, the x value does the changing. It's sign becomes the opposite of what it is now.

In plainer language,

• the x value = 4
• It's reflected across the y axis.
• It's value becomes - 4
• X' = (-4,-5)
• The y value of the point does not change.
