how do you know you have a direct variation in the relationship between two quantities?

According to Khan academy:

“Say you have y=2x. That is a direct variation and will always pass through the origin when graphed. When x is multiplied by a number, the y value will also be changed by that number. If you add a y-intercept and change y=2d to, for example, y=2x+2, the x and the y will no longer be related by a constant ratio.”

Hope this helps!
