Question

Pentagon OPQRS is shown on the coordinate plane below:

If pentagon OPQRS is dilated by a scale factor of 7/4 from the origin to create O'P'Q'R'S' , what is the ordered pair of point S? ( 4 points )

(8.75, 5.25)
(1.25, 0.75)
(1.75, 3.5)
(3.5, 8.75)

Answer 14

What are the coordinates of point S from the given figure?

Answer 15

3.5, 8.75?

Answer 16

?

Answer 17

Point S is 2 over and 5 up from the origin.
So, its coordinates are (2,5).

Answer 18

Thank you:)

Answer 19

For the dilation, multiply 2 by 7/4. What did you get?

Then, multiply 5 by 7/4. What do you get?

Those should be the ordered pair of S'.
I think you posted the original problem incorrectly (should be what is the ordered pair of point S'). S' coordinates come from multiplying each coordinate of the point S by 7/4.

What did you get for the coordinates of S' (read as S prime)
