Pentagon OPQRS is shown on the coordinate plane below:

Pentagon OPQRS on a coordinate plane with ordered pairs at O negative 1, 2, at P negative 5, 3, at Q negative 3, negative 2, and R 2, 1, at S 2, 5.

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 S'?

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

Respuesta :

7/4 = 1.75

S is at (2,5)

 multiply 2 by 1.75 and 5 by 1.75

2 * 1.75 = 3.50

5 *1.75 = 8.75

 so the new location of S would be (3.5,8.75)

The answer is D. 3.5,8.75 I just took the quiz and I got it right hope this helps!
