It is a special kind of linear function wear the line on a graph goes straight through the origin.

If x is directly proportional to y, then it means that for a value of x, y = cx, where c is some constant. For example, if a slice of Pizza costs a fixed cost (say 1 dollar), then the cost of your pizza meal is directly proportional to the number of slices you order. (Cost = 1 times number of slices.)
