The cost of the video downloads (in dollars) is given by the equation c = 2v, where c is the total cost of the videos and v is the number of videos. the constant of proportionality in the equation in terms of cost per video is (1/2,1,2,4) . in this example, the constant of proportionality is also the (total price, unit price) of the videos.

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.

i think it would be c
