Find the distance between points M and N. and if anyone could kinda explain how they got it so i can do the next ones on my own
WINSTONCH [101]

Answer:

\sqrt{13} = 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}

{3}^{2} + {2}^{2} = {c}^{2}

9 + 4 = {c}^{2}

13 = {c}^{2}

\sqrt{13} = c

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

_______________________________________________

Method #2

We can use the Distance Formula:

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

<em>N</em>[−3, 2] <em>M</em>[−6, 0]

\sqrt{[3 - 6]^{2} + [0 + 2]^{2}} = D

\sqrt{[-3]^{2} + 2^{2}} = D

\sqrt{9 + 4} = D

\sqrt{13} = 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.
