Linear equation definition math

What is a linear equation in math?

An equation that makes a straight line when it is graphed. Often written in the form y = mx+b. Equation of a Straight Line.

What is a linear equation easy definition?

The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line. An example of linear equation is y=mx + b.

What is linear equation Give 5 example?

Solve (i) 3x − 1=5 (ii) 4x +2=9 (iii) 6 − 2x = 1 (iv) 5x +1= −9 (v) 3x +1= x − 5 (vi) 6x − 1=3 − 2x (vii) 2 − 3(x − 2) = x + 4 (viii) 5(x − 1) + 1 = 2(x − 2). In general, a linear equation in one variable has just one solution, i.e., a unique solution.

What is the formula of linear equation?

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it’s pretty easy to find both intercepts (x and y).

Why is it called linear equation?

The left-hand side is an expression; we call it a linear expression, because if you used it in an equation with two variables, y = 2x+4, its graph would be a straight line. So the linear equation can be thought of very much in terms of a line.

How do you simplify a linear equation?

To solve linear equations we will make heavy use of the following facts.If a=b then a+c=b+c a + c = b + c for any c . If a=b then a−c=b−c a − c = b − c for any c . If a=b then ac=bc a c = b c for any c . If a=b then ac=bc a c = b c for any non-zero c .

What is linear function with example?

The linear function is popular in economics. Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable.

What are the 5 different forms of linear equations?
