The answers are very hard to see
I think the answer would be c but I'm not positive
I hope I help :)
According to Vertical Line test, a vertical line only intersect the graph of a function at one point. Among the choices given, x = 4 is a vertical line. So this line cannot intersect the graph of a function at more than one point. The other three would apply. So the answer choices are A, C and D.
Answer:
4
Step-by-step explanation:
The length of CD will be twice the distance from the midpoint to the endpoint
To calculate the length use the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (2, - 1) and (x₂, y₂ ) = (8, 3)
d = 2 × 
= 2 × 
= 2 × 
= 2 × 
= 2 × 2
= 4
← exact length
