1. You can tell the difference because the proportional one has the same slope while the inversely one has opposite reciprocal slope.
Directly proportional relationship is F=ma, F is directly proportional to a. Inversely proportional relationship is v=r/t, v is inversely proportional to t.
c, but the word is DIRECTLY, not dirctly!
Force is directly proportional to mass provided the acceleration is constant.
Inversely proportional means that one variable goes up while the other goes down. Directly proportional means that both variables increase or decrease at the same time. ex: The volume of a gas at constant pressure is inversely proportional to gas pressure, thus this means that as pressure increases, the volume of the gas will decrease. ex: The volume of a fixed amount of gas is directly proportional to absolute pressure, thus this means that when you heat a gas the volume also increases.
Directly. That's why you can't move a car by blowing on it.
Directly proportional: pressure and temperature (Boyle's Law and Charles's Law), inversely proportional: volume and pressure (Boyle's Law), volume and temperature (Charles's Law).
In directly proportional the two variable vary in the same "direction". So, if one increases, the other increases.In inversely proportional, the two variable vary in opposite "directions". So, if one increases, the other decreases.
Directly proportional relationship is F=ma, F is directly proportional to a. Inversely proportional relationship is v=r/t, v is inversely proportional to t.
The ideal gas law:PV = nRT Any two variables on the SAME SIDE of the equation are inversely proportional. Note that "R" is a constant; so the following are inversely proportional: P and V n and T (And any two variables on OPPOSITE sides are directly proportional.)
Two variables, X and Y are said to be in inversely proportional is X*Y - k where k is some non-zero constant. X and Y are said to be directly proportional if X = c*Y where c is some constant.
inversely proportional

The gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
The relationship between two variables whose ration is a constant value is a directly proportional relationship. An example of this is the ideal gas law, PV = nRT. Pressure and volume are directly proportional to the number of molecules of an ideal gas present ad the temperature.
Directly proportional. Greater speed - greater distance.
The statement current is directly proportional to voltage and inversely proportional to resistance is known as Ohm's Law.
Force is directly proportional to mass provided the acceleration is constant.
