Line segment AB on the coordinate plane stretches from (1,1) to (7,9). Line segment CD stretches from (-2,3) to (2,6). What is the ratio AB:CD of the lengths of these line segments A. 3:2
B 2:1
C 2:3
D 3:1

B 2:1

Step-by-step explanation:

Distance between two points:

Suppose that we have two points, and . The distance between them is given by:

In this question:

The length of the segments are given by the distance between its endpoints.

Line segment AB on the coordinate plane stretches from (1,1) to (7,9).

So its length is:

Line segment CD stretches from (-2,3) to (2,6).

What is the ratio AB:CD of the lengths of these line segments?

10:5 = 2:1

So the correct answer is given by option B.

111
