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.
Proportional quantities can be described by the equation y = k x, where k is a constant ratio. Step 2) we can tell that the relationship is directly proportional by looking at the graph. The graph is a straight line and it passes through the origin. So, the relationship is directly proportional. First, create a chart. Use points from the graph, such as (2, 20), (4, 40), (6, 60), (8, 80) and (10, 100)..
