Question

whitch of the following sums would be under radical symbol to find the distance between the points (7,-1) and (-8,-9)​

Answer 1

The distance between two points

d =
`√(289)` = 17

Explanation:

Explanation:-

Given points are ( 7,-1) and (-8,-9)

The distance between the two points

d =
`\sqrt{(x_(2)-x_(1))^(2) + (y_(2) - y_(1) )^(2) }`

d =
`\sqrt{(( (-8- 7 )^(2)+(-9-(-1))^(2) ) }`

`d = \sqrt{(( (-15 )^(2)+(-8)^(2) ) }\\d = √(225+64)`

d =
`√(289)`

d = 17

The distance between two points

d = 17
