#### 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 .

## How do you define linear?

1a(1) : of, relating to, resembling, or having a graph that is a line and especially a straight line : straight. (2) : involving a single dimension. b(1) : of the first degree with respect to one or more variables.

## 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?

There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form. We review all three in this article. There are three main forms of linear equations.

## How do you plot a linear equation?

To graph a linear equation, we can use the slope and y-intercept.Locate the y-intercept on the graph and plot the point.From this point, use the slope to find a second point and plot it.Draw the line that connects the two points.
