Question

Distance of -6,8 and 1,7

Answer 1

The distance between (-6,8) and (1,7) is 8.5 units.

Answer 2

d ≈ 7.07 units

Explanation:

calculate the distance d using the distance formula

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

with (x₁, y₁ ) = (- 6, 8 ) and (x₂, y₂ ) = (1, 7 )

d =
`√(((1-(-6))^2+(7-8)^2)`

=
`√((1+6)^2+(-1)^2)`

=
`√(7^2+1)`

=
`√(49+1)`

=
`√(50)`

≈ 7.07 units ( to 2 decimal places )
