Question

Find the distance between the points (1,10) and ( – 8, – 2). Round

Answer 1

15 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 ) = (1, 10 ) and (x₂, y₂ ) = (- 8, - 2 )

d =
`√((-8-1)^2+(-2-10)^2)`

=
`√((-9)^2+(-12)^2)`

=
`√(81+144)`

=
`√(225)`

= 15
