To perform a dilation on an ordered pair, you can follow these steps:
1. Identify the scale factor: The scale factor determines how much the figure will be enlarged or reduced. It can be a whole number, fraction, or decimal.
2. Multiply the x-coordinate of the ordered pair by the scale factor: Multiply the x-coordinate of the original point by the scale factor to find the new x-coordinate of the dilated point.
3. Multiply the y-coordinate of the ordered pair by the scale factor: Multiply the y-coordinate of the original point by the scale factor to find the new y-coordinate of the dilated point.
4. Write down the new ordered pair: Combine the new x-coordinate and the new y-coordinate to form the new ordered pair.
For example, let's say we have the ordered pair (2, 3) and we want to dilate it with a scale factor of 2.
1. The scale factor is 2.
2. Multiply the x-coordinate (2) by the scale factor (2): 2 * 2 = 4.
3. Multiply the y-coordinate (3) by the scale factor (2): 3 * 2 = 6.
4. The new ordered pair is (4, 6).
So, the dilated point of (2, 3) with a scale factor of 2 is (4, 6).
Remember, if the scale factor is greater than 1, the figure will be enlarged, and if it is between 0 and 1, the figure will be reduced.
