Best ResponseYou've already chosen the best response.0Basically that line isn't just purely up or down it's diagonal, that means that it has both an x and y component.

Best ResponseYou've already chosen the best response.0You can think of the line itself as a hypotenuse and the x and y components as different sides of a right angle triangle, ill draw a picture.
