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.
The graph of a direct relationship is very distinctive. If a graph is a straight line with a positive slope AND goes through the point (0, 0), then the relationship is direct. Definition: A quantity y is directly proportional to a quantity x if y = kx for some k > 0. k is called the constant of proportionality and this can be represented through a graph as shown below: Often just the term proportional is used to mean directly proportional.
