Question

which movement describes the translation below. 2 units left, 1 unit up 2 units right, 1 unit down 2 units right, 1 unit up 2 units left, 1 unit down

Explanation:

Step1: Observe the change in x - coordinate

The blue - colored triangle (image) is shifted to the left compared to the black - colored triangle (pre - image). In a coordinate plane, moving left means a decrease in the x - coordinate. Each point of the blue triangle is 2 units to the left of the corresponding point of the black triangle.

Step2: Observe the change in y - coordinate

The blue triangle is shifted 1 unit down compared to the black triangle. Moving down means a decrease in the y - coordinate.

Answer:

2 units left, 1 unit down
