Question

WHAT IS THE LENGTH OF THE LINE? SOMEONE SMART ANSWER THIS PLS:)

Answer 1

D

Explanation:

using the bottom left hand corner as the origin

calculate the length d using the distance formula

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

the coordinates of the ends of the line are then

(x₁, y₁ ) = (2, 8 ) and (x₂, y₂ ) = (12, 2 )

d =
`√((12-2)^2+(2-8)^2)`

=
`√(10)^2+(-6)^2)`

=
`√(100+36)`

=
`√(136)`
