ΔS’T’U’ is the result of reflecting ΔSTU over the y-axis. What are the coordinates of the vertices of ΔS’T’U’? S'( , 3), T'( , –1), U'( , –3)

To find the coordinates of the vertices of ΔS’T’U’ after reflecting ΔSTU over the y-axis, we need to change the sign of the x-coordinates of the points S, T, and U while keeping the y-coordinates the same.

Assuming the original coordinates are:

– S(x₁, 3)

– T(x₂, -1)

– U(x₃, -3)

After reflection over the y-axis, the new coordinates will be:

– S'(-x₁, 3)

– T'(-x₂, -1)

– U'(-x₃, -3)

Since you provided the coordinates for S’, T’, and U’:

– S'( , 3)

– T'( , -1)

– U'( , -3)

You just need to replace the blanks with the opposite signs of the original x-coordinates.

If you can provide the original coordinates for S, T, and U, I can give you the exact coordinates of S’, T’, and U’. Otherwise, follow the explanation to find the reflected points based on your original coordinates!
