Question

If quadrilateral BDMZ is a rhombus, which of the following ordered pairs could be a vertex?

(-9, 3)
(-9, 4)
(-10, 3)
(-10, 4)

Answer 1

with just the given info we should look at the fact that a rhombus has all sides the same length. BD has components
x=3
and
y=5
so all other sides must have that length of components (though two sides will have have y=3 and x=5 components).
so add or subtract 3 and 5 from each coordinate in various combinations until you find one of your choices.

Answer 2

i came out with D (-10,4)

Answer 3

sounds good to me :)

Answer 4

it was wrong
