Answer:
15
Step-by-step explanation:
Use the distance formula:
![\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28x_%7B2%7D-x_%7B1%7D%29%5E2%2B%28y_%7B2%7D-y_%7B1%7D%29%5E2%7D)
Insert values:
![(-9,7)=(x_{1},y_{1})\\\\(0,-5)=(x_{2},y_{2})\\\\\sqrt{(0-(-9))^2+(-5-7)^2}](https://tex.z-dn.net/?f=%28-9%2C7%29%3D%28x_%7B1%7D%2Cy_%7B1%7D%29%5C%5C%5C%5C%280%2C-5%29%3D%28x_%7B2%7D%2Cy_%7B2%7D%29%5C%5C%5C%5C%5Csqrt%7B%280-%28-9%29%29%5E2%2B%28-5-7%29%5E2%7D)
Two negatives make a positive. Simplify:
![\sqrt{(0+9)^2+(-5-7)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%280%2B9%29%5E2%2B%28-5-7%29%5E2%7D)
Simplify parentheses:
![\sqrt{(9)^2+(-12)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%289%29%5E2%2B%28-12%29%5E2%7D)
Simplify exponents:
![\sqrt{81+144}](https://tex.z-dn.net/?f=%5Csqrt%7B81%2B144%7D)
Simplify addition:
![\sqrt{225}](https://tex.z-dn.net/?f=%5Csqrt%7B225%7D)
Find the square root:
![\sqrt{225} =15](https://tex.z-dn.net/?f=%5Csqrt%7B225%7D%20%3D15)
The distance between the two points is 15.
