Question

What is the distance between the points (2,7) and (-8,1)

Answer 1

Explanation:

Given points ( 2 , 7) and ( - 8 , 1 )

Distance between two points

`√((x2 - x1 )+( y2 - y1))`

`√((2 + 8) + (7 - 1))`

`√(10 + 6)`

`√(16)`

`\sqrt {4}^(2)`

Therefore distance between two points is 4 units.
