The following is a rectangle. Find x and y using the information given. AB=2x DC=-7y-1 AD=x BC=-2y+10

OpenStudy (blockcolder):

Am I right to assume that the vertices of the rectangle looks like this?|dw:1373803503800:dw|

You should write equations that equalize opposite sides i.e. AB = DC and AD = BC in terms of x and y, and then solve two linear equations with two unknowns.
