Question

Quadrilateral BCDE is dilated by a scale factor of 2 with the center of dilation at the origin. If the coordinates of point B are (2, 1), the coordinates of B' are

Answer 1

The coordinates are B'(1,0.5)

Explanation:

Since the center of dilation is at the origin, we just divide the coordinates of the point by the scale factor.

In this question:

Scale factor of 2

B(2,1)

2/2 = 1

1/2 = 0.5

So, the coordinates are B'(1,0.5)
