Pleaseee help me....what will the y-coordinate of b' if ab is dilated by a factor of 2/5, centered at the origin. A=(2,2) B=(10,
sdas [7]

Answer:

The y-coordinate of B' is equal to 2

Step-by-step explanation:

step 1

Find the distance of AB

AB=10-2=8\ units

step 2

Find the length of A'B'

Multiply the length of AB by the scale factor

A'B'=8*\frac{2}{5}= 3.2\ units

step 3

Find the midpoint AB

M=(\frac{2+10}{2},\frac{2+2}{2} )

M=(6,2)

step 4

<em>Find the x-coordinate of B'</em>

The x-coordinate of B' is equal to the x-coordinate of midpoint plus the semi distance A'B'

6+\frac{3.2}{2}=6+1.6=7.6

<em>Find the y-coordinate of B'</em>

The y-coordinate of B' is equal to 2 (because is a horizontal line)
