Question

#4). Triangle ABC has the ordered pairs A(3,4); B(-9,5); and C(12, 3) and has been

dilated to produce the triangle with vertices A'(18, 32); B(-54, 30); and C'(72, 18).
Determine the scale factor for the ordered pairs. *
The scale factor for this ordered pairs is -

Answer 1

9514 1404 393

Answer:

6

Explanation:

Dilation about the origin multiplies each coordinate by the scale factor. We can find the scale factor by considering the x-coordinates of A and A'.

scale factor = Ax'/Ax = 18/3 = 6

The scale factor is 6.
