Question

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 P'?

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

Last question! Please help. Thank you!

Answer 1

Original point is
P(-5,3) a dilation of 7/4 will be applied
Dilation rule is
(x,y) --> (kx,ky) Where k is the scale factor which is 7/4
So (-5*7/4, 3* 7/4)
Simplify the multiplication process

Answer 2

After applying that multiplication we will get p'(-8.75, 5.25)
Make sense?

Answer 3

so A? Im really not good at this stuff :/

Answer 4

Yeah A good job

Answer 5

oh so i was right? its A?
