Question 955295: If the points A(-2,-1) , B(1,0) , C(x,3) and D(1,y) are the vertices of a parallelogram. Find the values of x and y?

You can put this solution on YOUR website! 
Based on the pattern, starting with (-2,-1) you move 3 units right and one unit up to get to (1,0).
So then
(1,y)+(3,1)=(x,3)
1+3=x
x=4
y+1=3
y=2
(4,3),(1,2)
