There isn't an option for which graph, so I can't give you a direct example. However, I can tell you the points the graph will have.
If y = 2x, that means that the points on the graph's line will be (x, 2x). To figure out which points, you can simply pick a random number as x and multiply by 2.
For instance: 2 • 2 = 4, so one point is (2, 4) 2 • 3 = 6, so another point is 3, 6) 2 • 4 = 8, so one more point is (4, 8)
The y value always equals twice or 2 times the x value
Plotting the points in coordinate plane , that is in x y plane,and joining them and producing them from both ends ,will give the equation of line, y=2 x, representing Direct variation.
