Look at the line segment below.
what is the length of the line segment?

a. 8 units

b. 9 units

c. 10 units

d. 12 units

The y coordinates of each point are 8. Since they are the same number, we can subtract the x coordinates: 10-2 = 8

Alternatively, you can place the points on a number line and count out the number of spaces. You should count out 8 spaces.

So the distance between the two points is 8 units
This is equivalent to saying that the line segment is 8 units long.

A) 8 units
