Triangle XYZ is shown on the coordinate plane below:Triangle XYZ on the coordinate plane with ordered pairs at X 3, negative 1, at Y 4, negative 4, at Z 1, negative 2If triangle XYZ is reflected across the line y = 1 to create triangle X'Y'Z', what is the ordered pair of X'?
Accepted Solution
A:
First, graph the triangle XYZ. Its points are: (3, -1) (4, -4) (1, -2) The triangle created is the first file attached. When reflected off of the line y = 1, it is one higher y than reflecting off the y axis. So, the coordinates are (1,-4) (3, 3) (4, 6)
