Your x can equal any number and your y can change depending on your x value. For example, if your x is equal 1, then your y is equal to 3 * 1 + 4 = 7. If your x is equal to 2, then your y is equal to 3 * 2 + 4 = 10. Then your x becomes a constant because the problem has stated that x is equal to 3.

The constant of proportionality is what determines the relationship between y and x. If r is the constant of proportionality then an example is y = rx . The value of y is dependant on how the given value of x is effected by the constant of proportionality.

In mathematics, proportionality indicates that two quantities or variables are related in a linear manner. If one quantity doubles in size, so does the other; if one of the variables diminishes to 1/10 of its former value, so does the other.

When one quantity increases constantly or decreases constantly with respect to another quantity then the two quantities are called directly proportional to each other. ... It means that, in this example, the proportionality constant is 0.5.

Technically two quantities are proportional if one is always a constant multiple of the other, and from a strictly mathematical point of view, there is nothing to stop the constant from being negative.

A constant of proportionality can be any value, including fractions and decimals. The main difference between the constant of proportionality and a unit rate is how they are written. For example, the constant of proportionality is written , but the unit rate would be written.

Students calculate the rate of change also know as the constant of proportionality (k = y/x) which is the constant ratio between two proportional quantities y/x denoted by the symbol k which may be a positive rational number. The x value is directly proportional to the y value such as in the equation y = kx.

Now we have a constant of proportionality which is y=2x. To get y, we have to multiply x by 2. In your question, the constant of proportionality already jump out at us which is to get y, we have to multiply x by 7. Therefore the constant of proportionality is y=7x.
