The endpoints of one diagonal of a The The endpoints of one diagonal of a rhombus are (0, 8) and (8, 4). If the coordinates of the 3rd vertex are (1, 0), what are the coordinates of the 4th vertex?
(7, 12)
(7, 8)
(8, 4)
(4, 12)

sketch graph
from y = 8 must go down 4
so at y = 12
from x = 0 must go right 7
so at x = 7
so
(7,12)
