1. Question 2

2. Question 2 Triangle ABC is shown on this coordinate grid.
Triangle ABC is dilated with the origin as the center of the dilation. Which ordered pair could represent the image of point C (5, 2) after the dilation?
a) (2.5, 1) b) (5, -2) c) (7.5, 4.5) d) (-1, -4)
When you dilate something, you make it bigger/larger. In this case, you’re looking for something that is smaller than the shape. For this case, the answer would be (a) because if you double it, it will become (5, 2).
If students chose B, they might be reflecting it over the x axis
If students chose C, they probably added 2.5 to both numbers
If studetns chose D, they subtracted 2.5 to both numbers.
