Alinear equationis anyequationthat can be written in the form $ax+by=0$, where a and b are real numbers and x is a variable. This form is sometimes called the standard form of a linear equation.

No variable in alinear equationis raised to a power greater than 1. Linear equationsare those equations that are of the first order.

Standard form of Linear Equation is $Ax+By+C\text{ â¶Ä‰}=\text{ â¶Ä‰}0$, where A, B and C are any integer.

In order to rewrite the equation$y=−4x+3$in standard form add 4x to both sides as follows:

$$\begin{gathered} y=−4x+3 \\ y+4x=−4x+3+4x \\ y+4x=3 \\ y+4x−3=3−3\text{ } \\ 4x+y−3=0 \end{gathered}$$

The equation is now in standard form where $A=4,B=1\text{and}C=–3$. Since the variables in the equation has the highest exponent as 1, so the equation is linear.

Yes, this is a linear equation and the standard form is:$4x+y−3=0$.
