(2,6) top right
(?, ?) bottom left
(5,-3) bottom right

You can put this solution on YOUR website! "Three vertices of a parallelogram are shown in the figure below. Give the coordinates of the fourth vertex."
(-4,8) Top left
(2,6) top right
(?, ?) bottom left
(5,-3) bottom right
Next we draw a horizontal (red) line from (2,6) left until we are directly
below the point (-4,8):
Next we draw a vertical (red) line up to the point (-4,8):
Now observe, by counting blocks, (1) that the horizontal red line goes
6 units left of (2,6), and that (2) the vertical line goes 2 units up
to the point (4,8).
Next, we do the same thing at the lower right point (5,-3).
We draw a red horizontal line 6 uints left of (5,-3) and then
2 unites upward, like this:
By counting blocks we see that that red vertical line ended up at (1,1),
so that's the answer. Now we can draw in the complete parallelogram:
