Consider the two planes.

Revolt · Accepted Answer

line d.

Question 2

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

They are parallel because their slopes are equal.

Question 3

On a coordinate plane, a line goes through (negative 3, 2) and (0, 1). A point is at (3, 4).

Revolt · Accepted Answer

y = 3x − 5

Question 4

On a coordinate plane, a line goes through (1, negative 1) and (4, 2). A point is at (2, 5).

Revolt · Accepted Answer

y − 5 = −(x − 2)

Question 5

On a coordinate plane, a line goes through (negative 3, 3) and (negative 2, 1). A point is at (4, 1).

Revolt · Accepted Answer

y − 1 = −2(x − 4)

Question 6

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

(–6, 10)

Question 7

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 8

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 9

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 10

Lines c and d are intersected by line p. At the intersection of lines c and p, the bottom left angle is (3 x + 45) degrees. At the intersection of lines d and p, the uppercase left angle is 81 degrees.
