The distance between two points (x1,y1) and (x2,y2) is given by the following formula:
![\sqrt[]{(x2-x1)^2+(y2-y1)^2}](https://img.qammunity.org/2023/formulas/mathematics/college/lv29jygnvr92r2akqmo57wrhy4130lwc7w.png)
In this case, we are given the points (6,2) and (1,8), by replacing 6 for x1, 1 for x2, 2 for y1, and 8 for y2, we get:
![\sqrt[]{(1-6)^2+(8-2})^2=\sqrt[]{(-5)^2+(6)^2}=\sqrt[]{25+36}=\sqrt[]{61}\approx7.8](https://img.qammunity.org/2023/formulas/mathematics/college/nt33tua37mw7q99iluk16t2kazjuqw0mon.png)
Then, the distance between these points is around 7.8 units
