Graph the image of the given triangle after the transformation with the rule (x, y)→(x−1, y+2) . select the "polygon" button from the tool bar to plot your triangle. you may use the "move" button to move the triangle after it is created. polygonmove undoredoreset

The transformation is merely a translation of points vertically and horizontally. The original triangle must have its original coordinates. All you have to do is subtract 1 from their x-coordinate, and add 2 units to their y-coordinates. For example, if the original coordinate is (1,2), then the translated point would now be (0,4). Once you get all the translated points, you can plot them as the new translated triangle.

Idon’t know what the answer is i wish i could
