Question

what are the coordinates of B', the image of point B, after dilation by a scale factor of 1.5 centered at (5, -5)​

Answer 1

Answer:

B' = (7.5, -7.5)

Step-by-step explanation:

Given the coordinate B = (x, y)

If the coordinate is dilated by factor of k, the resulting coordinate will be (kx, ky)

For the coordinate (5, -5), if dilated by a factor of 1.5, the required coordinate will be;

B'= (1.5(5), 1.5(-5))

B' = (7.5, -7.5)

This gives the required coordinate
