What is a constant ratio of two variables related proportionally?
It is the constant of proportionality.
What is the constant of portionality?
If two variables are directly proportional to one another then the constant of proportionality is the ratio of their values. If they are in inverse proportion then the constant of proportionality is the product of their values.
What relationship exist between two variables when their ratio is constant?
Direct proportionality. Their graph would be a straight line through the origin, with the slope equal to the ratio.
What are the two way to determine if the relationship between two quantities are proportional?
Graphical: If two variables are proportional, the graph of one of the variables against the other is a straight line through the origin.Algebraic: If the ratio of the two variables is a constant.
Is y-2.5x a proportional relationship or no?
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.
What is a constant ratio of two variables related proportionally?
It is the constant of proportionality.
What is a constant ratio of two variables that are related proportionally?
It is the constant of proportionality.
What is direct veriation?
Two variables related in such a way that their values always have a constant ratio directly vary.
What is the relationship in which the ratio of the manipulated variables and the responding variables is constant?
Direct Proportion
What is constant of preportionality?
The constant of proportionality between two variables is the ratio of one to the other.
What relationship exists between two variable when their ratio is a constant?
Two variables whose ratio is constant have a linear relationship. The first variable is the second multiplied by the constant.
What is the relationship between two variables quantities with a constant ratio?
It is a direct proportion.
What does constant of proportion mean?
If two variables are in direct relationship then the ratio of the two variables is known as the constant of proportion between them. In algebraic form, if X and Y are the two variables, then direct proportionality implies that Y = cX and c is the constant of proportionality.
When the ratio of two variables is constant their relationship can be described as what?
dependent
How do you recognize a proportional relationships in a table?
If you take any pair of variables in the table, their ratio is a constant.
What is the constant of portionality?
If two variables are directly proportional to one another then the constant of proportionality is the ratio of their values. If they are in inverse proportion then the constant of proportionality is the product of their values.
How do you find the constant and slope for direct variation equations?
For a direct variation equation the constant MUST be 0. Then the ratio of a pair of values of the two variables is the slope.
