Question

show that the points (-4,-1) (-2,-4) (4,0) (2,3) are the vertices point of a rectangle

Answer 1

I hope this is correct

Answer 2

Let us take A(-4,-1), B(-2,-4), C(4,0), D(2,3)


use slope formula
slope of AB=slope of CD
slope of AD=slope of BC
slope of AC=slope of BD

if all the condition will satisfied it is the points form the rectangle
