Question

Need more geometry help. One diagonal of a rhombus has endpoints (-9, -3) and (-7, -9).

What are the endpoints of the other diagonal?

Answer 1

find the slope of this line
rhombus's have all four congruent sides, so find the distance between these two points
move over that many points and draw a diagonal of the same slope
not the endpoints

Answer 2

\[m={-9-(-3)\over-7-(-9)}\]\[m={-6\over2}\]\[m=-3\]

distance formula:\[\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\]

i got you started, solve it through
