Answer:
C. undefined.
Step-by-step explanation:
Find the slope of the line, using the following equation:
m = (y₂ - y₁)/(x₂ - x₁)
Find two points that are located on the line.
Let:
(x₁ , y₁) = (-4 , 0)
(x₂ , y₂) = (-4 , 1)
Plug in the corresponding numbers into the corresponding variables.
m = (1 - 0)/(-4 - (-4))
Note that when you have two negative signs directly next to each other, it becomes an addition:
m = (1)/(-4 + 4) = 1/0
You cannot have a slope of rise 1, run 0, so your answer is undefined.
C. undefined.
