Question

What is the distance between points (1, 9) and (9, -6

Answer 1

17 units

Explanation:

Calculate the distance d using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (1, 9) and (x₂, y₂ ) = (9, - 6)

d =
`√((9-1)^2+(-6-9)^2)`

=
`√(8^2+(-15)^2)`

=
`√(64+225)`

=
`√(289)`

= 17
