Apr 17, 2015. To graph the direct variation #y=5/2x#, determine two points on the line. If #x=0, y=(5/2*0)=0# Point = #(0,0)#. If #x=2, y=(5/cancel 2*cancel 2/1)=5# Point = #(2,5)#. Plot the two points and draw a straight line through the points. graph{y=5/2x [-7.605, 12.395, -3.345, 6.655]}r.
Interpretation according to the definition of direct variation: When the radius (the independent variable) is doubled, the circumference (the dependent variable) is also doubled. This is how the relationship of the variables C (circumference) and r (radius) is described in direct variation. I hope that you realize that it's not just y=kx. If you know the key phrases and the definition (and the relationship), you can solve real-life situation problem involving direct variation.
