Question

State weather each equation or is a linear function. write yes or no. explain. 3y-4x=20

Answer 1

YES. A linear equation with two variables and three constants can be represented as $Ax + By = C$. There, equation, $3y-4x=20$ is a linear equation.

A linear function is a type of equation that has one or two different variables.

A linear function having two variables with three constants can be represented in its standard form as:

$Ax + By = C$

Where y is a function of x:

A, B, and C are constants.

x and y are the two variables

In the equation given, $3y-4x=20$, there are:

Three constants - 3, -4, and 20;

Two variables - x and y.

Therefore we can state that the equation is a function.
