What is regression coefficient and correlation coefficient?
The strength of the linear relationship between the two variables in the regression equation is the correlation coefficient, r, and is always a value between -1 and 1, inclusive. The regression coefficient is the slope of the line of the regression equation.
When you insert 0x and 0y into a linear equation to make a matrix what order do you add them in?
When inserting (0x) and (0y) into a linear equation to create a matrix, you typically represent the coefficients of the variables in the order they appear in the equation. For example, if the equation is (0x + 0y = b), you would create a matrix where the first column corresponds to the coefficient of (x) (0) and the second column corresponds to the coefficient of (y) (0). Thus, the order is important for accurately reflecting the relationships between the variables.
What is the slope for the equation y equals -2x plus 5?
The slope would be -2 (moving 2 units down and one across). When you have a linear equation, the slope is always the variable's coefficient.
How does a coefficient relate to a slope?
A coefficient in a linear equation represents the rate of change of the dependent variable with respect to the independent variable, which is essentially the slope of the line. In the equation of a line, typically expressed as (y = mx + b), the coefficient (m) indicates how much (y) changes for a one-unit increase in (x). Thus, the coefficient directly defines the steepness or direction of the slope: a positive coefficient indicates an upward slope, while a negative coefficient indicates a downward slope.
Which is the correct set of coefficient for the equation below?
The correct set of coefficient for an equation depends with the equation in question. There are many types of equations.
What is the coefficient of x in a decreasing linear equation?

What is the coefficient in a linear equation called?
Due to some perversity in human nature, it is called a coefficient!
What is regression coefficient and correlation coefficient?

Why can't an equal 0 in a quadratic equation?
a is the coefficient of the x2 term. If is a = 0, then it is no longer a quadratic - it is just a linear equation, and the quadratic formula will not work to solve it.
What are quadratic equations?
In mathematics, a quadratic equation is a polynomial equation of the second degree. The general form is : where a≠ 0. (For if a = 0, the equation becomes a linear equation.) The letters a, b, and c are called coefficients: the quadratic coefficient a is the coefficient of x2, the linear coefficient b is the coefficient of x, and c is the constant coefficient, also called the free term or constant term. Quadratic equations are called quadratic because quadratus is Latin for "square"; in the leading term the variable is squared. A quadratic equation with real or complex coefficients has two (not necessarily distinct) solutions, called roots, which may or may not be real, given by the quadratic formula: : where the symbol "±" indicates that both : and are solutions.
What is the coefficient in an equation?
A coefficient is a number paired with a variable. For example, in the equation4x+2x=16, the numbers 4 and 2 would be coefficients.Coefficients are the factors (usually constants) which are multiplied by the variables in each term. For example, in a second-degree polynomial equation,y = ax2 + bx + ca is called the quadratic coefficient, b is the linear coefficient and c is the constant term.

Is a linear equation the same as a function?
No a linear equation are not the same as a linear function. The linear function is written as Ax+By=C. The linear equation is f{x}=m+b.
What is the coefficient in the equation?
The coefficient in an equation is the number that is multiplied by a variable. It is the numerical factor that appears in front of the variable.
Does the coefficient of linear expansion depends upon length?
yes,according to relation coefficient of linear expansion depends upon original length.
