Using the distance formula;
![|d|=\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2}](https://tex.z-dn.net/?f=%7Cd%7C%3D%5Csqrt%5B%5D%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D)
From the points given:
x₁=-1 y₁=-2 x₂=8 y₂=10
substitute the values into the formula;
![|d|=\sqrt[]{(8+1)^2+(10+2)^2}](https://tex.z-dn.net/?f=%7Cd%7C%3D%5Csqrt%5B%5D%7B%288%2B1%29%5E2%2B%2810%2B2%29%5E2%7D)
![=\sqrt[]{9^2+12^2}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B%5D%7B9%5E2%2B12%5E2%7D)
![=\sqrt[]{81+144}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B%5D%7B81%2B144%7D)
![=\sqrt[]{225}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B%5D%7B225%7D)

The distance is 15 units.
