Answer:
![3\sqrt{13}](https://tex.z-dn.net/?f=3%5Csqrt%7B13%7D)
Step-by-step explanation:
Hi there!
We want to find the distance between the points (2, -2) and (-4, 7).
To do that, we can use the distance formula.
The distance formula is given as
, where
and
are points
We have everything needed to find the distance, but let's label the values of the points to avoid any confusion
![x_1=2\\y_1=-2\\x_2=-4\\y_2=7](https://tex.z-dn.net/?f=x_1%3D2%5C%5Cy_1%3D-2%5C%5Cx_2%3D-4%5C%5Cy_2%3D7)
Now substitute those values into the formula and solve
![\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D)
![\sqrt{(-4-2)^2+(7--2)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-4-2%29%5E2%2B%287--2%29%5E2%7D)
Simplify
![\sqrt{(-4-2)^2+(7+2)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-4-2%29%5E2%2B%287%2B2%29%5E2%7D)
![\sqrt{(-6)^2+(9)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-6%29%5E2%2B%289%29%5E2%7D)
Square the numbers under the radical
![\sqrt{36+81}](https://tex.z-dn.net/?f=%5Csqrt%7B36%2B81%7D)
Add the numbers under the radical together
![\sqrt{117}](https://tex.z-dn.net/?f=%5Csqrt%7B117%7D)
Simplify the square root
![3\sqrt{13}](https://tex.z-dn.net/?f=3%5Csqrt%7B13%7D)
Hope this helps!
