Problem 1

Answer: 6.7

----------------

Work Shown:

The two points are
(x_1,y_1) = (1,-2) and
(x_2,y_2) = (4,4)

Apply the distance formula to get the following


d = √((x_1 - x_2)^2 + (y_1 - y_2)^2)\\\\d = √((1-4)^2 + (-2-4)^2)\\\\d = √((-3)^2 + (-6)^2)\\\\d = √(9 + 36)\\\\d = √(45)\\\\d \approx 6.7082039\\\\d \approx 6.7\\\\

The distance between the two endpoints is roughly 6.7 units. This is the same as saying the segment is roughly 6.7 units long.

Problem 2

Answer: 3.6

----------------

Work Shown:

We'll use the distance formula here as well.

This time we have the two points
(x_1,y_1) = (3,1) and
(x_2,y_2) = (5,-2)

The distance between them is...


d = √((x_1 - x_2)^2 + (y_1 - y_2)^2)\\\\d = √((3-5)^2 + (1-(-2))^2)\\\\d = √((3-5)^2 + (1+2)^2)\\\\d = √((-2)^2 + (3)^2)\\\\d = √(4 + 9)\\\\d = √(13)\\\\d \approx 3.6055513\\\\d \approx 3.6\\\\

This distance is approximate.
