Question

How do you graph the direct variation equation `y=5/2x`?

Answer 1

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.
