Sketch the image of A (-3,5) after the described glide reflection. Translation: (x, y)=(x - 2, y + 5)
Reflection: in y =4

Plz HELP me out I really don’t understand this!

Translation (x, y) = (x - 2, y + 5)

(x, y) = (x - 2, y + 5)

(-3, 5) = (-3 - 2, 5 + 5)

(-3, 5) = (-5, 10)

So this means that point A' (-5, 10) is your translation of point A (-3, 5) .

Now let us look at the reflection. It says to reflect across the y = 4. Basically you will draw a horizontal straight line on 4. Count how many units is point A (-3, 5) is. Then do it on the other side of the line. Point A' (-3, 3) is reflected across y = 4 of point A (-3, 5).

Hope this helps, thank you !!

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
