Use the Distance Formula to find the distance between each pair of points. Round to the nearest tenth if necessary. 5. P(1, 1), Q(–1, –1)

6. E(1/2,4 1/4),F(5,-1/2)

Given:

The pair of points.

5. P(1, 1), Q(–1, –1)

6.

To find:

The distance between the pair of points.

Solution:

Distance formula:

5.

The distance between the pair of points P(1, 1) and Q(–1, –1) is:

Therefore, the distance between P and Q is .

6.

The distance between the pair of point is:

On further simplification, we get

Therefore, the distance between E and F is 6.5 units.
