Question

The vertices of a trapezoid are shown below.

P(0, 0), Q(2, 0), R(2, 5), S(0, 10)

This trapezoid is dilated about the origin by a scale factor of 3. What is the location of point S'?
(3, 13)

(0, 13)

(3, 30)

(0, 30)

Answer 1

to dilate about the origin simply multiply all the (x,y) points byt th escale factor (which is 3 in this case

So Q=(2,0) => Q' = (3,0)

do that for S to get the answer...

Answer 2

i got d

Answer 3

If you understand the concept, and are confident with your answer - go with it

Answer 4

i got it right!

Answer 5

so do i do that for every question like that? multiply it by the scale factor?

Answer 6

if the dilation is about the origin - then yes that is correct
