x is directly proportional to y if when x is increased (or decreased) by a relative amount then the same relative change occurs in y.
So, if x is doubled, for example, then y is also doubled.
Examples are:
1. Weight is equal to mass * gravity. Here mass and weight are directly proportional (when measured in the same gravitational field). For example, if we double the mass then the weight is also doubled.
2. In electronics there is a law called Ohm's Law which states: voltage = current * resistance (V = IR). Here the voltage is directly proportional to both current and resistance. For example, if we halve either the current or resistance then the voltage is also halved.
There are lots of other examples you could find.
it is some wrods and maybe some numbers
Two variables, X and Y, are said to be in direct proportion if X/Y is a constant. Equivalently, Y = cX for some constant c.

x and y are in direct proportion if there is some positive constant c such that y = cx
direct proportion: y=kx inverse proportion: y=k/x
Two variables, X and Y, are said to be in direct proportion if X/Y is a constant. Equivalently, Y = cX for some constant c.
when both increaes its direct proportion and when one increase and othe decreases its inverse proportion.

Yes it does rely on direct proportion.

the three kinds of proportions are indirect proportion, direct proportion and thepartitive proportion
