8. If the points (-2,-1),(1,0), (x,3) and (l,y) form a parallelogram, find the values of x and y
please fast​

Answer 1

Answer:

x=4 and y=2

Step-by-step explanation:

Let the vertices of the parallelogram be A(-2, -1), B(1, 0), C(x, 3) and D(1, y). Since the diagonals of a parallelogram bisect each other the coordinates of the mid-point of AC = coordinates of the mid-point of BD.

(-2+x/2 , -1+3/2) = (1+1/2 , 0+y/2)

(-2+x/2, 1) = (1,y/2)

∴ x = 4, y = 2

Answer 2

Answer:

if these points are in an order then

x= -2

and y=2
