Pentagon OPQRS is shown on the coordinate plane below:
http://prnt.sc/d0arf8

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'?
(−3.5, −8.75)
(−0.75, −0.5)
(−5.25, −3.5)
(−2.33, −3.5)

and please explain because this confuses me

Since the center of Dilation is assumed to be the Origin, have you considered multiplying the coordinates by 7/4?
