Triangle xyz is shown on the coordinate plane below: if triangle xyz is reflected across the line y = 1 to create triangle x'y'z', what is the ordered pair of x'? a. (3,3) b. (3,1) c. (-1,-1) d. (-3,-1)

The line y=1 is the horizontal line passing through the point (0, 1). We have drawn it with red.

The reflection across this line of each point X, Y, and Z is such that the distance of each  X, Y, and Z is equal to the distance of each X', Y', and Z', respectively, to the red line.

According to our drawing, we see that the coordinates of X' are (3, 3).
