Revolt · Accepted Answer

C: vertical angles theorem

Question 2

Which points lie on the line that passes through point P and is parallel to the given line? Select three options.

Revolt · Accepted Answer

B: (–1, 3); C: (–2, 2); E: (–5, –1)

Question 3

On a coordinate plane, 2 lines are shown. Line A B has points (negative 4, negative 2) and (4, 4). Line C D has points (0, negative 3) and (4, 0).

Revolt · Accepted Answer

A: They are parallel because their slopes are equal.

Question 4

On a coordinate plane, line P Q goes through (negative 6, 4) and (4, negative 4). Point R is at (4, 2).

Revolt · Accepted Answer

B: (–4, –8)

Question 5

In the diagram, DC is 10 units and BC is 6 units.

Revolt · Accepted Answer

C: 12 units

Question 6

On a coordinate plane, 2 lines are shown. Line P Q has points (negative 5, 3) and (5, 1). Line R S has points (negative 4, negative 2) and (0, negative 4).

Revolt · Accepted Answer

C: They are not parallel because their slopes are not equal.
