The distance between points is calculated through the equation,
D = sqrt ((x₂ - x₁)² + (y₂ - y₁)²)
We calculate for the distances of each of the pairs.
(-3,4) and (3, 4)
D = sqrt ((4 - 4)² + (3 --3)²) = 6
(-5,3) and (-5,11)
D = sqrt ((-5 --5)² +(11 - 3)²) = 8
(-20,-18) and (-22,-21)
D = sqrt ((-20 --22)² + (-18 --21)²) = 3.6
(2,4) and origin
D = sqrt ((2 - 0)² + (4 - 0)²) = 4.5
(7,8) and (-2,20)
D = sqrt ((-2 - 7)² + (8 - 20)²) = 15
Arranging the distances will give us an answer of C, D, A, B, E
The answer is letter C.
