Answer 1

To find the coordinates A' and B' after a dilation of the points A(-6, 3) and B(-12, 9) with a scale factor of 13 centered at the origin, you will multiply each coordinate of the original points by the scale factor.

For point A(-6, 3):

• A' = (x * scale factor, y * scale factor)
• A' = (-6 * 13, 3 * 13)
• A' = (-78, 39)

For point B(-12, 9):

• B' = (x * scale factor, y * scale factor)
• B' = (-12 * 13, 9 * 13)
• B' = (-156, 117)

Thus, the new coordinates after the dilation will be:

• A' = (-78, 39)
• B' = (-156, 117)
