Correct answers are A, C and D.
Parallel lines have equal slopes.
4x - y = -5 ⇒ y = 4x + 5 ⇒ m = 4
8x - 2y = -10 ⇒ 4x - y = -5 ⇒ m = 4
4x + y = -2 ⇒ y = -4x - 2 ⇒ m = -4
4x - y = 2 ⇒ y = 4x - 2 ⇒ m = 4

Answer:
Step-by-step explanation:
The complete question in the attached figure
step 1
Find the measure of angle QPZ
we kno that
---> by supplementary angles (form a linear pair)
we have
---> given value
substitute
step 2
Find the measure of angle YSV
we know that
When two lines are crossed by another line, <em><u>Alternate Exterior Angles</u></em> are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal. If the two lines are parallel then the alternate exterior angles are congruent.
In this problem
The transversal is the line XY
The two parallel lines are RQ and VW
therefore
---> by alternate exterior angle
we have
therefore
