To determine if a situation represents a proportional relationship, you can compare the rates of two quantities. If the ratio of one quantity to the other remains constant regardless of the values, the relationship is proportional. For example, in a situation where you are analyzing the cost of items, if the price per item stays the same as the quantity changes, then it indicates a proportional relationship. Conversely, if the ratio changes, the relationship is not proportional.
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.
To find an unknown value in a proportional relationship, you can set up a ratio equation based on the known values. For example, if you have a proportional relationship expressed as ( \frac{a}{b} = \frac{c}{d} ), where ( a ) and ( b ) are known values, and ( c ) is the unknown, you can cross-multiply to solve for ( c ) by rearranging the equation to ( c = \frac{a \cdot d}{b} ). This allows you to calculate the unknown value while maintaining the proportional relationship.
In the context of a proportional relationship, where the relationship can be expressed as (y = kx) for some constant (k), the equation (n = 2) does not represent a proportional relationship. It is simply a constant value rather than a variable relationship between two quantities. For a relationship to be proportional, there must be a consistent ratio between two variables that can vary.
To determine if an answer represents a non-proportional relationship, check if the ratio between the two quantities remains constant. If the ratio changes as one quantity increases or decreases, or if the graph of the relationship does not pass through the origin, it indicates a non-proportional relationship. Additionally, if there is a fixed amount added or subtracted rather than multiplied or divided, the relationship is also non-proportional.

Proportional is when it is proportional.
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.
It is a relationship of direct proportion if and only if the graph is a straight line which passes through the origin. It is an inverse proportional relationship if the graph is a rectangular hyperbola. A typical example of an inverse proportions is the relationship between speed and the time taken for a journey.
You cannot represent a proportional relationship using an equation.
It is true in the case of inversely proportional relationship.
A proportional relationship exists when two variables are related by a constant ratio. In the expression y-2.5x, there is no constant multiplier connecting y and x, indicating a non-proportional relationship. If the relationship were proportional, the expression would be in the form y = kx, where k is a constant.

If the ratio between each pair of values is the same then the relationship is proportional. If even one of the ratios is different then it is not proportional.

If the graph is a straight line through the origin, sloping upwards to the right, then it is a proportional linear relationship.
