If y equals kx then what is the relationship between x y and k?
Various options: y is directly proportional to k, with x as the constant of proportionality; y is directly proportional to x, with k as the constant of proportionality; x is inversely proportional to k, with y as the constant of proportionality; x is directly proportional to y, with 1/k as the constant of proportionality; k is directly proportional to y, with 1/x as the constant of proportionality; and k is inversely proportional to x, with y as the constant of proportionality.
What is the symbols of inversely proportional and directly proportional?
The greek letter "alpha" (α) for both. If x is directly proportional to y, you could say x α y. For inversely proportional, you would say something like x α 1/y, or x α y^-1, as in, directly proportional to the inverse.
How do you prove that x and y are directly proportional with the equation Y equals 8X-3?

If y is proportional to the square of x fully explain what happens when x is doubled?
Example with numbers: Y = X2 Y = (2)2 Y = 4 ==== So if Y is ( directly ) proportional to X2 when X is doubled Y is increased four times.
What is inversly proportional?
x is inversely proportional to y when x = 1/y.
