Find the distance between the points A(13,2) and B(7,10)
Anna007 [38]

Answer:

10 = D

Step-by-step explanation:

Method #1

We can draw a <em>right triangle</em> on the graph upon where the points are located and use the Pythagorean Theorem:

{a}^{2} + {b}^{2} = {c}^{2}

{6}^{2} + {8}^{2} = {c}^{2}

36 + 64 = {c}^{2}

100 = {c}^{2}

10 = c

* Whenever we talk about distance, we ONLY want the NON-NEGATIVE root.

_______________________________________________

Method #2

Or, we can use the Distance Formula:

\sqrt{[-x_1 + x_2]^{2} + [-y_1 + y_2]^{2}} = D

<em>B</em>[7, 10] <em>A</em>[13, 2]

\sqrt{[-2 + 10]^{2} + [-13 + 7]^{2}} = D

\sqrt{8^{2} + [-6]^{2}} = D

\sqrt{64 + 36} = D

\sqrt{100} = D

10 = D

* Whenever we talk about distance, we ONLY want the NON-NEGATIVE root.

** You see? It does not matter which method you choose, as long as you are doing the work correctly.

I am delighted to assist you anytime.
