We have xy=2
xy+y=2+y
x+0=2+y
x2=22+y
x2=0+y
y=x2
Now, select values for x at random to build the graph
Let x=1, then y=12=3
Let x=0, then y=02=2
Let x=2, then y=22=0
So, we have the points: (-1,-3), (0,-2), (2,0)
Now mark these point on the graph and draw a line through them. Here you are.

We have xy=2. Rearrange it into standart form
y=x2
Select random values for x to make the data for your future graph
If x=2, then y=22=4
If x=0, then y=02=2
If x=3, then y=32=1
The points are: (2,4), (0,2), (3,1). Make a graph using these points.
