Answer 1

Step-by-step explanation:

5. Join PR and QS, intersecting each other at 0.

Weknow that the diagonals of the parallelogram bisect each other.

So,O is the mid-point of PR and QS.

Coordinates of mid-point of PR= ( 2+3/2,4+6/2)=(5/2,10/2)= coordinates of mid point of QS

Coordinates of mid-point of QS=(0+5/2,3+y/2)=(5/2,3+y/2).

Now, these points coincides at the point O.

(5/2,3+y/2)=(5/2,5)

3+y/2 = 5

3+y=10

y=7
