Answer: Vertex = (-1, -21) y-intercept = (0,-11)
Step-by-step explanation:
The two angles are a linear pair.
(Explanations down below!)
Linear pair angles must add up to 180 degrees. You can tell that the two angles add up to 180 degrees because they form a straight line (which is 180 degrees).
Complementary angles add up to 90 degrees. The two angles are not complementary because they do not form a 90 degree angle (right triangle, square in corner, like a L shape).
Vertical angles are opposite each other and are equal to one another. These angles are adjacent to each other and do not look similar.
Divide both sides by -6 and don't forget to flip the inequality symbol
-7>d
d<-7
Answer: D.
Step-by-step explanation: If you look closely, putting a 100 wouldn't make sense
