Question

Find the distance between two points (-9, 5) and (-9, -5)

Answer 1

10

Explanation:

(-9,5) (-9,-5)

`x_(1) = -9\\y_(1) =5\\x_(2) =-9\\y_(2) =-5`

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

`\sqrt{(-9-(-9)^(2) +(-5-5)^(2) }`

`\sqrt{(-9+9)^(2)+(-5-5)^(2) }`

`\sqrt{(0)^(2)+(-10)^(2) }`

`√(0+100)`

`√(100) =` 10
