Which of the following equations is an example of a direct variation ? A. x + 2y = 6 B. x = 4 C. y = 3 D. y = 3.14

OpenStudy (anonymous):

direct variation is when a point goes through the origin.

OpenStudy (anonymous):

plug in 0 for x to find y and plug in 0 for y to find x. if these numbers make 0,0--then it is a DV

OpenStudy (anonymous):

so it would be A?

OpenStudy (anonymous):

show me your work

OpenStudy (anonymous):

( anything that passes through the origin is DV, proportional, and linear)
