Answer:
C. Yes, 3.5.
Step-by-step explanation:
If there is a relationship of direct proportionality for every ordered pair of the table, then the constant of proportionality must the same for every ordered pair. The constant of proportionality ( ) is described by the following expression:
) is described by the following expression:
 (1)
 (1)
Where:
 - Input.

 - Output.
 - Output.
If we know that  ,
,  and
 and  , then the constants of proportionalities of each ordered pair are, respectively:
, then the constants of proportionalities of each ordered pair are, respectively:









Since  , the constant of proportionality is 3.5.
, the constant of proportionality is 3.5.

Answer:
B. BC ≅ LM
Step-by-step explanation:
BC corresponds to LM. These are the only two sides without the hash marks that represent congruence. If the marks were there to indicate that the sides are congruent, then the triangles could be proved congruent by SSS.
