Will give brainiest ! tuvw has vertices t(1,-3),u(3,-1),v(6,-4),and w(4,-6).determine if quadrilateral tuvw is a parallelogram.
a.
no, tuvw quadrilateral is not a parallelogram.
b.
yes, tuvw quadrilateral s a parallelogram because there are two pairs of parallel sides.
c.
yes, tuvw quadrilateral is a parallelogram because the slopes of the diagonals are perpendicular.
d.
there is not enough information to determine.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
