Question

The point A had the coordinates (7, 4) and is dilated from the origin by a scale factor of 2. What are the coordinates of A'?

A. A' is at (14, 8).
B. A' is at (3.5, 2).
C. A' is at (7, 2).
D. A' is at (14, 4).

Answer 1

The coordinates of A' after dilating point A (7, 4) from the origin by a scale factor of 2 are (14, 8).

Step-by-step explanation:

To find the coordinates of A' after dilating point A (7, 4) from the origin by a scale factor of 2, multiply each coordinate of A by the scale factor. So, the x-coordinate of A' = 2 * 7 = 14 and the y-coordinate of A' = 2 * 4 = 8.

Therefore, A' has the coordinates (14, 8).
