Answer 1

Hello!

Distance between two points (2,9) and (6,3) - 

1. Take the Absolute Difference between the X points 2 and 6. The Absolute Difference is 4. 
2. Square 4 = 16 
3. Take the Absolute Difference between the Y points 9 and 3. The absolute Difference is 12. 
4. Square 12 = 144 
5 Add 144 + 16 = 160 
6. Take the Square root of 160
