draw each paralelogram in blue and draw both diagonals in red/pink.Find the coordinates of the intersection of the diagonals.

EXPLANATION
Given the coordinates of the parallelogram COWS as follows:
C=(-3,2) ; O=(4,5) ; W=(2,-3) ; S=(-5,-6)
Plotting the graph:
Now, we can get the intersecction of the diagonals by intersecting the segment CW with OS as shown as follows:
In conclusion, the intersection point is at (-0.5, -0.5)
