The coordinates of the endpoints of [tex]\overline{AB}[/tex] and [tex]\overline{CD}[/tex] are [tex]\(A(3, 6), B(8, 7), C(3, 3)\)[/tex], and [tex]\(D(8, 4)\)[/tex]. Which statement describes how [tex]\overline{AB}[/tex] and [tex]\overline{CD}[/tex] are related?

A. [tex]\overline{AB} \parallel \overline{CD}[/tex]
B. [tex]\overline{AB} \perp \overline{CD}[/tex], and [tex]\overline{AB}[/tex] bisects [tex]\overline{CD}[/tex].
C. [tex]\overline{AB} \perp \overline{CD}[/tex], but [tex]\overline{AB}[/tex] does not bisect [tex]\overline{CD}[/tex].
D. [tex]\overline{AB}[/tex] is neither parallel nor perpendicular to [tex]\overline{CD}[/tex].



Answer :

To determine how the line segments [tex]\(\overline{A B}\)[/tex] and [tex]\(\overline{C D}\)[/tex] are related, we evaluate their slopes and compare them. We have the coordinates of the endpoints as follows:
- [tex]\( A(3, 6) \)[/tex]
- [tex]\( B(8, 7) \)[/tex]
- [tex]\( C(3, 3) \)[/tex]
- [tex]\( D(8, 4) \)[/tex]

### Step-by-Step Solution:

#### Step 1: Calculate the slope of [tex]\(\overline{A B}\)[/tex]

The formula for the slope between two points [tex]\((x_1, y_1)\)[/tex] and [tex]\((x_2, y_2)\)[/tex] is:
[tex]\[ m = \frac{y_2 - y_1}{x_2 - x_1} \][/tex]

For [tex]\(\overline{A B}\)[/tex], using points [tex]\(A(3, 6)\)[/tex] and [tex]\(B(8, 7)\)[/tex]:
[tex]\[ m_{AB} = \frac{7 - 6}{8 - 3} = \frac{1}{5} = 0.2 \][/tex]

#### Step 2: Calculate the slope of [tex]\(\overline{C D}\)[/tex]

Using the same formula for the slope, for points [tex]\(C(3, 3)\)[/tex] and [tex]\(D(8, 4)\)[/tex]:
[tex]\[ m_{CD} = \frac{4 - 3}{8 - 3} = \frac{1}{5} = 0.2 \][/tex]

#### Step 3: Compare the slopes

The slopes for both line segments are:
[tex]\[ m_{AB} = 0.2 \][/tex]
[tex]\[ m_{CD} = 0.2 \][/tex]

Since the slopes [tex]\(m_{AB}\)[/tex] and [tex]\(m_{CD}\)[/tex] are equal, this indicates that [tex]\(\overline{A B}\)[/tex] is parallel to [tex]\(\overline{C D}\)[/tex].

### Conclusion:

Given that the slopes are equal, the correct statement describing the relationship between [tex]\(\overline{A B}\)[/tex] and [tex]\(\overline{C D}\)[/tex] is:

A. [tex]\( \overline{A B} \parallel \overline{C D} \)[/tex]

Thus, the line segments [tex]\(\overline{A B}\)[/tex] and [tex]\(\overline{C D}\)[/tex] are parallel.
