Just plotted some points on a coordinate graph and connected the pointsHe realizes that one more points would complete a parallelogram where should he plot the point

Explanation
The given points in the question are as follows
[tex]\left(1,5\right),\left(7,3\right),\left(6,0\right)[/tex]To find which of the point is a parallelogram we can test all the given options
For (0,2), we will have the image below.
The above image represents ta parallelogram as the distance between the x and y coordinates for opposite sides are the same.
Answer: Option 1
