Question 1

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

They are not parallel because their slopes are not equal.

Question 2

On a coordinate plane, a line goes through (negative 4, 0) and (4, negative 4). A point is at (2, 3).

Revolt · Accepted Answer

x + 2y = 8

Question 3

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

Revolt · Accepted Answer

12 units

Question 4

Two parallel lines, e and f, are crossed by two transversals.

Revolt · Accepted Answer

m15 = 97°

Question 5

Which diagram shows lines that must be parallel lines cut by a transversal?

Revolt · Accepted Answer

2 horizontal lines are intersected by another line. At the intersection with the first line, the bottom right angle is 91 degrees. At the intersection with the second line, the top right angle is 89 degrees.

Question 6

Lines e and f are intersected by line a. At the intersection of lines a and e, the bottom right angle is 72 degrees. At the intersection of lines a and f, the uppercase right angle is 108 degrees.
