The coordinates of the endpoints of A⁢B― and C⁢D― are *A*(3, 6), *B*(8, 7), *C*(3, 3), and *D*(8, 4). Which statement describes how A⁢B― and C⁢D― are related?

 **A.** 

A⁢B― || C⁢D―

 **B.** 

A⁢B― ⊥ C⁢D―, and A⁢B― bisects C⁢D―.

 **C.** 

A⁢B― ⊥ C⁢D―, but A⁢B― does not bisect C⁢D―.

 **D.** 

A⁢B― is neither parallel nor perpendicular to C⁢D―.


To determine how the line segments \( \overline{AB} \) and \( \overline{CD} \) are related, we need to calculate their slopes. If the slopes are equal, the lines are parallel. If the slopes are negative reciprocals of each other, the lines are perpendicular. If neither condition holds, they are neither parallel nor perpendicular.

### Step 1: Find the slope of \( \overline{AB} \)
The formula for the slope between two points \( (x_1, y_1) \) and \( (x_2, y_2) \) is:

\[
\text{slope of } \overline{AB} = \frac{y_2 - y_1}{x_2 - x_1}
\]

For \( A(3, 6) \) and \( B(8, 7) \):

\[
\text{slope of } \overline{AB} = \frac{7 - 6}{8 - 3} = \frac{1}{5}
\]

### Step 2: Find the slope of \( \overline{CD} \)

For \( C(3, 3) \) and \( D(8, 4) \):

\[
\text{slope of } \overline{CD} = \frac{4 - 3}{8 - 3} = \frac{1}{5}
\]

### Step 3: Compare the slopes

Since the slope of \( \overline{AB} \) is \( \frac{1}{5} \) and the slope of \( \overline{CD} \) is also \( \frac{1}{5} \), the lines are **parallel**.

Thus, the correct answer is:

**A.** \( \overline{AB} \parallel \overline{CD} \)
