Question

Consider AB in the coordinate plane below. A( 2,2) B(10,2). What would be the y- coordinate of B' if AB was dialated by the factor of 2/5 centered at the orgin?

A. 16/5
B. 4/5
C. 2
D.34/5

Answer 1

Answer:it is b

Explanation:

Answer 2

9514 1404 393

Answer:

B. 4/5

Explanation:

When dilation is centered on the origin, each coordinate is multiplied by the dilation factor:

B'y= k·By

B'y = (2/5)(2)

B'y = 4/5 . . . . . . . y-coordinate of B'
