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.
In the following equation y varies directly with x, and k is called the constant of variation: Another form of variation is the inverse variation which works when there is a relationship between two variables in which the product is a constant.When one variable increases the other decreases in proportion so that the product is unchanged.hen we have a variation where one quantity varies as the product of two or more other quantities we have what is called joint variation: Videolesson: State whether each equation represents a direct, inverse or joint variation: xy=7 y=xz x/y=4. 1  Pre-Algebra. 2  Algebra 1. 3  Algebra 2. 4  Geometry. 5  Sat.
