what does it mean when they say tell wheather the equation represents direct variation. if so then give the constant of variaton

the problem is:
2y-5x=0

  • algebra 2 -

    y= 5x/2 So as x doubles, so does y. That is a direct variation.

    The constant here is 5/2

  • algebra 2 -

    so it is just the slope of the line??

  • algebra 2 -

    yes.
