Question

Which lines are parallel? Check all that apply.

(A) 80, 91.5
(B) 91.5, Doll
(C) Doll, 80.5
(D) None of the lines are parallel.

Answer 1

To determine which lines are parallel, we need to examine their slopes. None of the given lines are parallel as their slopes differ. The correct answer is (D) None of the lines are parallel.

Step-by-step explanation:

To determine which lines are parallel, we need to examine the slopes of the lines. Two lines are parallel if and only if their slopes are equal. Let's evaluate the slopes of the given lines:

1. A: 80, B: 91.5
2. A: 91.5, B: Doll
3. A: Doll, B: 80.5

Since there are different values on each side of the comma in each option, we can conclude that none of the lines are parallel to each other. Therefore, the correct answer is (D) None of the lines are parallel.
