What is the difference between a variable and a formula?
A variable is a single term that is free to change its value. A formula is a relationship between terms which describes one variable in terms of several others, which usually has 1 variable on the left hand side, and at least 1 on the other side. For example (if x and y are variables, then y = x² is a formula of y in terms of x).
Is there a relationship between X and Y?
if X lies between 6&12 and Y lies between 24&36 the Y/X will ie between
How do you write the equation that represents the relationship between x and y on a accompanying table?
x=y
What is increasing linearly?
A variable Y is said to increase linearly with another variable X if every increase of a fixed amount in X results in another fixed increase in Y. In terms of a graph, the relationship is a straight line.
What are the independent and depent variables?
You can tell which is the independent variable and which is the dependent variable by changing the equation into an "if/then" statement. Example: y = 3x In this example, x is the independent variable and y is the dependent variable. If you give me x, I will tell you y. If x = 1, then y = 3 If x = 2, then y = 6 So you give me the independent variable, and then I will be able to determine the dependent variable.
What is a mathematical relationship?
In a linear relationship such as represented in the equation x= b+ay. The relationship between the x and y is a direct variation. This basically means that in the above equation/situation the value of the y variable is proportional to the value of the x variable. In other words the x and y increase or decrease proportionately. If the x value decreases the y value decreases. If the x value increases so does the y value. Now in a quadratic relationship it is a little different in that this kind of function is actually in the shape of a parabola. The equation for this relationship is ax2 + bx + c = y. The parabolic relationship exists when one variable depends on the square of another and this relationship is often expressed in saying that the y variable varies directly with the square of the x variable.
What is an inverse relationship between two variables?
An inverse relationship is one in which as the value of one variable increases, the value of the second variable decreases. For example, in the equation y = 1/x, as y gets bigger, x gets smaller and as x gets bigger, y gets smaller.
When there is a straight line on a graph what type of relationship there is between the dependent variable and the independent variable?
It depends on the slope ofthe linear graph. if y=x then the relationship is 1:1 if y=3x then the relationship is 3:1 if y=2/7x then the relationship is 2:7

What shows the relationship between two variables?
A function expresses the relationship between two or more variables. A function can be expressed as a mathematical equation or as a graph. In general, a function expresses a the effect an independent variable has on the dependent variable..For example, in the classic linear function:y = mx + bx and y are the variables (m is said to be the slope, and b is the constant). This function expresses the mathematical relationship between the variables x and y. In this function, x is said to be the independent variable, and the function destines the y variable to be dependent upon the value of x.
What happens to z when x is doubled and y stays the same?
That would depend on the relationship between x, y, and z.That would depend on the relationship between x, y, and z.That would depend on the relationship between x, y, and z.That would depend on the relationship between x, y, and z.
What does the equation for a linear relationship stand for?
y=mx+b is the equation for a linear relationship. y= the dependant variable m= the slope of the line x= the independent variable b= the y-intercept
Why is it important to find the slope of a line?
A line is used to describe the relationship between two variables, often an independent variable that is measured on the x-axis, and a dependent variable that is measured along the y-axis.The slope of the line tells you how much y will change for every unit change (change of -1 or +1) in x.A line is used to describe the relationship between two variables, often an independent variable that is measured on the x-axis, and a dependent variable that is measured along the y-axis.The slope of the line tells you how much y will change for every unit change (change of -1 or +1) in x.A line is used to describe the relationship between two variables, often an independent variable that is measured on the x-axis, and a dependent variable that is measured along the y-axis.The slope of the line tells you how much y will change for every unit change (change of -1 or +1) in x.A line is used to describe the relationship between two variables, often an independent variable that is measured on the x-axis, and a dependent variable that is measured along the y-axis.The slope of the line tells you how much y will change for every unit change (change of -1 or +1) in x.
Is x squared plus 5y minus x equals 7 a function?
No. It is an equation. A function would link the variable x to another variable - possibly denoted by y. It is a relationship between two (or more) variables.
What is the definition of a proportional relationship?
An arbitrary variable (x) is equal to a constant (k) times another variable (y). Formula: x=ky
Is there a relationship between X and Y?
if X lies between 6&12 and Y lies between 24&36 the Y/X will ie between
What is the relationship between the dependent and independat variables?
The dependent variable is influenced by changes in the independent variable. The dependent variable's values depend on the values of the independent variable. This relationship is often explored through statistical analysis in research studies.
