### What is definition of inverse and direct proportion?

Direct proportion means as the independent variable increases, the dependent variable increases, and vice versa. Inverse propostion means just the opposite. As the independent variable increses, the dependent variable decreases, and vice versa.

### 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.

### What is the direct proportion?

Two variables, X and Y, are said to be in direct proportion if X/Y is a constant. Equivalently, Y = cX for some constant c.

### What does it mean when two variables have a positive correlation?

A positive correlation between two variables means that there is a direct correlation between the variables. As one variable increases, the other variable will also increase.

### Can you find the constant of proportionality when given a certain situation?

If the variables are in direct or inverse proportion then yes; otherwise no.

### What is the definition of direct SQUARE proportion?

In a nonlinear graph showing the relationship between two variables where one is related o the second power of he other. This will no be in a straight line, but will curve upward and it is known as direct square proportion.

### How are proportions related to direct variations?

If two variable, X and Y are in direct variation, then the proportion of X/Y or Y/X has a constant value.

### What is proportional relationship in math terms?

Two variables are proportional to one another if there is a simple relationship, of the following form:The variables X and Y are indirect proportion if Y = c*Xandinverse proportion if Y = d/X or, equivalently, X*Y = dfor some non-zero constants c and d, called the constants of proportionality.Note that if Y is inversely proportional to X, then Y is directly proportional to the variable 1/XThe graph of a direct proportion is a straight line through the origin, with slope = constant of proportionality.

### How do you determine direct and inverse proportion on graphs?

If the variables x and y are in direct proportion then the graph of y against x is a straight line through the origin. If the variables x and y are in inverse proportion then the graph of y against x is a rectangular hyperbola. Alternatively, the graph of y against 1/x (or 1/y against x) is a straight line through the origin.

### Differentiate direct proportion from inverse proportion?

when both increaes its direct proportion and when one increase and othe decreases its inverse proportion.

### What are the 4 kinds of proportionality in physics?

### A straight line on a graph means there is what kind of relationship between the dependent variable and the independent variable.?

A straight line shows direct proportion. That means that equal changes in the independent variable always produce the same change in the dependent variable.

### What are the 4 types of proportion?

### What are the two kinds of proportion?

the two kinds of proportion are direct proportion and partitive proportion.

### What is the meaning of direct square proportion?

A variable Y is said to be in direct square proportion of a variable X ifthey are both 0 together andif variable X takes any value p then Y takes the value c*p2 where c is a constant, known as the constant of [square] proportionality.A typical example would by X = linear measure of a regular 2 or 3-d shape and Y = its surface area.

### What is a direct proportion?

Two quantities x and y are said to be in direct proportion if whenever the value of x increase (or decrease), then the value of y increases (or decrease) in such a way that the ratio x/y remains constant.

### What does x equals 2n mean?

It means that the variable x is twice as much as variable n. x is in direct proportion to n (or x varies directly as n) with the constant of proportionality = 2.

### How does graphing relationships help you determine whether the relationship is proportional or not?

If the points lie on a straight line through the origin, the two variables are in direct proportion.
