If the algebraic equation is linear, in the form y = mx + b, the slope is simply m; the difference in y of any 2 points divided by the difference in x of those points (rise over run). If the equation is non-linear, the slope is the first derivative of that equation, from calculus. You woul need to know calculus to solve in this case. The slope will vary from point to point, unlike the linear case, where slope is constant.

No because when you place x in terms of y, you get y = 1/x ( by dividing both the sides by x). This is not linear because the power of x is (-1) and for a linear relationship, you need the power of x to be (1).

A linear equation is a straight line that is going at an angle usually, and if you just have a y it will be going straight up,so I would assume that you would always need a x intercept. so yes. Yes, unless the slope of x is 0.

To write a linear equation use the formula y = mx + b . You just substitute all the variables in. I will go through each variable, and tell you the procedures. *Keep y just how it is. *m is the slope. You can find the slope by doing rise over run. *x can be left the same at this time, but a teacher will explain about this as you will need to substitute different things for y and x eventually once you get into higher levels of math. * b is the y-intercept. The y-intercept is where the line touches x = 0 .

It is a certain type of equation used in Algebra. It uses letters to replace numbers and the aim of cracking the equation is to find the value of the letter. Such as: 4b+2=26 ....you would need to find the value of 'b'. -2( 4b= 24 )-2 ( b=6 )divided by 4 I've just solved the equation.

a+b=16 is a linear equation in two variables. The variables are a and b. To solve a linear equation in 2 variables we need more information. We need either another equation, or a value to put in for a or b.Since we have neither, there is no more we can do.

You need another equation to make this a linear equation so you can solve for both variables. One equation with two variables is not enough to determine the correct answer.

The answer is every point on the line in the Cartesian plane which is defined by the equation. You have one linear equation in two unknown variables. In order to solve for two variables you need two independent linear equations.

The question contains a linear expression in two variables. It is not an equation (nor inequality) and so cannot be solved. Furthermore, with two variables, you need two linear equations.

The domain. It need not be the "independent variable" since the variables could be interdependent.

A function of one variable is of the form y=f(x) where all you need to know in order to get values for y is the value of the independent variable, x. A function of two variables is of the form z=f(x,y) where you need to know the values of both x and y to get a value for z. A linear equation is simply and algebraic equation where all variables, regardless of how many there are, are raised to the power of one.

You cannot solve one linear equation in two unknown variables (x and y), although some non-linear equations will suffice. You need two independent linear equations. All you can do is express one of the variables in terms of the other, but that is not solving the equation.

A linear equation in n variables, x1, x2, ..., xn is an equation of the forma1x1 + a2x2 + ... + anxn = y where the ai are constants.A system of linear equations is a set of m linear equations in n unknown variables. There need not be any relationship between m and n. The system may have none, one or many solutions.

Since this is a linear equation with 2 variables, it is an unsolvable equation as a and b could be anything, to find an exact answer you need another equation that relates to the first one.

Standard. You need a linear equation in two variables for slope-intercept form.

The solution to a system on linear equations in nunknown variables are ordered n-tuples such that their values satisfy each of the equations in the system. There need not be a solution or there can be more than one solutions.
