Ответ:
The locations of A' and B' are A'(0, 4) and B'(4, 0); lines f and f' are parallel.
Step-by-step explanation:
Dilation about the origin multiplies each coordinate value by the dilation factor. A(0, 2) becomes A'(0, 4) when dilated by a factor of 2. Likewise, B(2, 0) becomes B'(4, 0).
Dilation does not change the direction of lines, so all dilated image lines are parallel to the corresponding original lines.
