Question

Find the distance between A(-6, -4)and B(9, -12)​

Answer 1

17 units

Explanation:

Answer 2

17 units

Explanation:

Calculate the distance using the distance formula

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

with (x₁, y₁ ) = A(- 6, - 4) and (x₂, y₂ ) = B(9, - 12)

AB =
`√((9+6)^2+(-12+4)^2)`

=
`√(15^2+(-8)^2)`

=
`√(225+64)`

=
`√(289)`

= 17 units
