what are the different forms of linear equations in 2 variables?

There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form.

The standard form of such an equation is Ax + By + C = 0 or Ax + By = C. When you rearrange this equation to get y by itself on the left side, it takes the form y = mx +b. This is called slope intercept form because m is equal to the slope of the line, and b is the value of y when x = 0, which makes it the y-intercept.

Standard form is just another way to write a linear equation equation along with slope intercept form and point slope form. The constants, A, B, and C, must be integers. And A must be positive. An example of a line in standard form would be: 4x+7y=12 Here, 4, 7, and 12 are all whole numbers, and 4 is positive.

Polynomials in two variables are algebraic expressions consisting of terms in the form axnym a x n y m . The degree of each term in a polynomial in two variables is the sum of the exponents in each term and the degree of the polynomial is the largest such sum.

A linear equation in two variables doesn't involve any power higher than one for either variable. It has the general form Ax + By + C = 0, where A, B and C are constants. ... A quadratic equation, on the other hand, involves one of the variables raised to the second power.

Thanks. it is a linear equation because the highest order of exponents is equal to 1. the equation is in standard form.

Coefficients are the number part of the terms with variables. In 3x2 + 2y + 7xy + 5, the coefficient of the first term is 3. The coefficient of the second term is 2, and the coefficient of the third term is 7. If a term consists of only variables, its coefficient is 1.

A system of linear inequalities in two variables consists of at least two linear inequalities in the same variables. The solution of a linear inequality is the ordered pair that is a solution to all inequalities in the system and the graph of the linear inequality is the graph of all solutions of the system.

Slope-intercept form is y = mx + b form, where m represents the slope, and b represents the y-intercept. So if the equation of a line is y = 3/4 x - 2, then the line is written in slope intercept form, or y = mx + b form, with m = 3/4 and b = -2.

The slope of a line is the rate of change of y with respect to x. The slope-intercept form of a linear equation is y = mx + b, where m is the slope of the line. ... The standard form of a linear equation is Ax + By = C. When we want to find the slope of the line represented by this equation, we have two options.

A linear equation in two variables describes a relationship in which the value of one of the variables depends on the value of the other variable. In a linear equation in x and y, x is called x is the independent variable and y depends on it. ... You can then plot the points named by each (x,y) pair on a coordinate grid.

You are probably already familiar with the slope-intercept form of a line, y = mx + b. The standard form is just another way to write this equation, and is defined as Ax + By = C, where A, B, and C are real numbers, and A and B are both not zero (see note below about other requirements).

Algebraically, a linear equation typically takes the form y = mx + b, where m and b are constants, x is the independent variable, y is the dependent variable.
