Question

Given A(4, -1), what are the coordinates of A’ under the coordinate rule (x, y) → (x - 1, y + 2)?

Answer 1

To find point A' using the given coordinate rule (x, y) → (x - 1, y + 2), we subtract 1 from the x-coordinate and add 2 to the y-coordinate of point A(4, -1), resulting in the new coordinates for A' being (3, 1).

Step-by-step explanation:

The question is asking to apply a coordinate rule to point A(4, -1) to find the coordinates of A' after the transformation. The coordinate rule given is (x, y) → (x - 1, y + 2). This means that we will subtract 1 from the x-coordinate and add 2 to the y-coordinate of point A to find point A'.

To find A', we apply the rule to the x and y values of A:

• x-coordinate of A': 4 - 1 = 3
• y-coordinate of A': -1 + 2 = 1

Therefore, the coordinates of A' after applying the transformation are (3, 1).
