Question

Use the distance formula to find the length of the segment A(1, 2) to B(7, 2)

A. 36

B. 10

C. 3

D. 6

Answer 1

D

Explanation:

Using the distance formula

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

with (x₁, y₁ ) = A (1, 2 ) and (x₂, y₂ ) = B (7, 2 )

d =
`√((7-1)^2+(2-2)^2)`

=
`√(6^2+0^2)`

=
`√(36+0)`

=
`√(36)`

= 6
