Question

Show that the points (-2,9), (4,6), (1,0), and (-5, 3) are the vertices of a square.

Answer 1

I don't understand if there is a particular way to solve this or if they're just asking me to plot the points and draw a square??

Answer 2

Use the distance formula to find the distances of all points from the others.
You'll get all 4 distance as the same proving that it is either a rhombus or a square!
Now find the slope of the sides and prove that
slope1.slope2 = -1
Got it? :)
