How do you find the rate of change--or slope--in a two variable equation?

For a straight line,
if A = (x1 , y1) and B = (x2 , y2) are any two points on the line, then the slope is
(y2 - y1)/(x2 - x1) provided x2 is not the same as x1.
More generally, if the equation is y = f(x) then the rate of change in y is dy/dx or f'(x), the derivative of the function f(x).

How do you find the variable in fraction equation?
It depends on the form of the equation.
What does SOLVE stand for in math?
"Solve an equation" means "find out, for which values of the variable or variables is the equation true".
A number multiplied by a variable?
A number, multiplied by a variable is part of an Algebraic equation. A person can find out the value of the variable if they divide each side by the number that is next to the variable. For example, if the equation is 5x = 60, divide each side by 5 and the answer is x = 12.
What is x to the fifth power?
x is a variable. You need to find the variable to complete the equation. ex. x = 1 x to the power of 5 (1x5x5x5x5x5)
What does x mean in a math equation?
x is a variable. You do not have to know what its value is. In that equation you have to find the value of x, so if you already know what x stands for then you know the answer

What reduces an equation that has two variables to an equation that has one variable It is the possible to find the solution for this variable?

What does solve the equation mean?
Find values for the variable that satisfy the equation, that is if you replace those values for the variable into the original equation, the equation becomes a true statement.
How can you find a variable in math?
You find, or construct, an equation or set of equations which express the unknown variable in terms of other variables. Then you solve the equation(s), using algebra.You find, or construct, an equation or set of equations which express the unknown variable in terms of other variables.

What is the goal of solving an equation with one variable?
The goal is to find what value or values the variable may have, to make the equation true.

What is a equation with Variable?
An equation with a variable is a math problem with a missing number that you have to find out using some specific steps that you are taught. Example: 4+n=5. If you want to find out what the variable is, you have to do the OPPOSITE OPPERATION and find it out. So I would take the answer, and do the opposite operation and then the answer is the variable. Of course there are MUCH harder variable equations. :D
When you find the value of a variable you solve or check an equation?
when you find the value, you SOLVED the equation. you CHECK the equation when you substitute the value in the variables place and check that the equation is true.
How do you do math applications?
find the variable(s). then write the equation(s). finally simplify the equation(s)
What does SOLVE stand for in math?
"Solve an equation" means "find out, for which values of the variable or variables is the equation true".
