Answer:

Explanation:
Method #1
We can draw a right triangle on the graph upon where the points are located and use the Pythagorean Theorem:





* 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](https://img.qammunity.org/2020/formulas/mathematics/middle-school/niykja1j1yn7zcorca81ex20wguu7bn7uj.png)
N[−3, 2] M[−6, 0]
![\sqrt{[3 - 6]^(2) + [0 + 2]^(2)} = D](https://img.qammunity.org/2020/formulas/mathematics/middle-school/cyxfwt4d1nscwr4t6wvryd4hurqe6vng4i.png)
![\sqrt{[-3]^(2) + 2^(2)} = D](https://img.qammunity.org/2020/formulas/mathematics/middle-school/rzf4a3r69egaex2z5x7o21fnitytu0jdn0.png)
