Select the correct answers.
Given the points \( A(-7,0), B(3,4), C(5,-1) \), and \( D(-5,-5) \), study the lines relationship.
Select 2 choice(s)
\( \overline{B C} \) is perpendicular to \( \overline{C D} \).
The slope of \( \overline{C D} \) is \( \frac{2}{5} \).
The slope of \( \overline{A B} \) is \( \frac{5}{2} \). The slope of \( \overline{B C} \) is \( -\frac{2}{5} \).
\( \overline{C D} \) is perpendicular to \( \overline{A B} \). \( \overline{A D} \) is perpendicular to \( \overline{B C} \).
