Which points are 4 units apart?
xz_007 [3.2K]

The points that are 4 units apart are B and D

<h3>Complete question</h3>

Which points are 4 units apart? On a coordinate plane, point A is at (-2, 4), point B is at (3, -6), point C is at (-1, 0), point D is at (3, -2).

B and C

C and D

A and C

B and D

<h3>How to determine the points?</h3>

To do this, we simply calculate the distance using the following equation

d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2

Using the given points, we have:

BC = \sqrt{(3+ 1)^2 + (-6 -0)^2} = 7.2

CD = \sqrt{(-1 - 3)^2 + (0 +2)^2} = 4.5

AC = \sqrt{(-2 + 1)^2 + (4 -0)^2} = 4.1

BD = \sqrt{(3 - 3)^2 + (-6 +2)^2} = 4

Hence, the points that are 4 units apart are B and D
