B:is proportional because it goes through the origin and several other points
C: c is proportional becuase it goes through the origin and is liner (straight line)

y = x + 95

y = 42 + 95

y=137 mm hg

you need to give us more information since we can't answer

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
