The relation between n and t is directly proportional with constant as 7.
The relationship between two values where their ratio equals a constant number is known as a direct proportion or direct variation. It is symbolised by the proportional sign∝ . Since the other variable is reversed in this case, the inversely proportional relationship is really represented by the same symbol.
When direct proportion is convert into equality it gives a constant known as constant of proportionality.
Just as r∝ t . r=ct, here c is constant of proportionality.
Equations with constants of proportionality are known as linear equations, and they take the following form:
y=mx+b
where "m" stands for the proportionality constant and "b" is the y-intercept.
Making a function whose n value (number of trees) directly varies with time is required of us (t). Time, then, is an independent variable because it affects how many trees there are. We therefore know that "t" will be our "x" value and "n" will be our "y." Finally, we are aware that the proportionality constant, "m," is 7.
y=mx+b;
n=7t
where "t" is the amount of time in years and "n" is the number of trees that the typical American uses to make paper products.
