Question

Pentagon OPQRS is shown on the coordinate plane below.



If pentagon OPQRS is dilated by a scale factor of seven over four from the origin, to create O’P’Q’R’S’, what is the ordered pair of point Q’?
Answer

(-3.5, -8.75)

(-0.75, -0.5)

(-5.25, -3.5)

(-2.33, -3.5)

Answer 1

Can you post the picture?

Answer 2

oops i forgot ..yea

Answer 3

Okay, sorry for the late reply, my internet went down for a little while..
We know that Q is located at (-3, -2) and that the scale factor is 7/4 from the origin

You simply have to multiply the component by the scale factor, and you'll get Q'
(-3(7/4), -2(7/4))
(-5.25, -3.5)

So the answer is C)

Answer 4

oh...ok thanks ! so for the other ones like P and R and S i would just have to do the same? multiply it by 7/4?
