Question 191571: Points x(-1,1), y(3,5), and z(17,1) are coordinates of three vertices of a parrallelogram. Waht are the possible coordinates of w, the fourth vertex?

You can put this solution on YOUR website!
distance between points x and y are x=+4, y=+4
add these to (17,1) and we arrive at ( 21,5)

subtract these from (17,1) and we arrive at (13,-3)

Both make parallelograms
