Question

Which answer explains one way that the length of this line segment can be determined?

A.
Add 3 + 1.

B.
Add 6 + 1.

C.
Subtract 3 – 1.

D.
Subtract 6 – 1.

Answer 1

C grath it to see

Answer 2

well i have a lot oiof expiirence so i dont need a whole grath i just imagine

Answer 3

well the points are the form (x,y)

both y coordinates are the same, so this will be a horizontal line...

can you see that?

Answer 4

So the distance between the two , is just a horizontal distance from x=1 to x=3

Distance AB = subtract 3 - 1

Answer 5

More formally , the distance magnitude is the hypotenuse of a right triangle

\[\left| AB \right| \sqrt{(By-Ay)^2 + (Bx - Ax)^2}\]

By = 6
Ay = 6

Ax = 3
Bx = 3
\[\left| AB \right| = \sqrt{(0 - 0)^2 + (3 - 1)^2} = \sqrt{4} = 2\]
