Chapter 2: Q27. (page 66)

Write each equation in standard form. Identify $A, B$ and $C$ .
$y = - 3 x + 4$

Short Answer

Expert verified

The required values are $A = 3, B = 1, C = 4$ .

Step by step solution

– Standard form of a linear equation.

The standard form of a linear equation is $A x + B y = C$ , where $A \geq 0, A$ and B are not both zero.

– Rewrite the given linear equation in the standard form.

The given equation is:

$y = - 3 x + 4$

Add 3x on both sides.

$\begin{matrix} y + 3 x = - 3 x + 4 + 3 x \\ y + 3 x = 4 \\ 3 x + y = 4 \end{matrix}$

– Find the required values.

Now compare the equation $3 x + y = 4$ with the standard form of the linear equation $A x + B y = C$ to find the values of $A, B, C$ .

$\begin{matrix} A = 3 \\ B = 1 \\ C = 4 \end{matrix}$

Thus, the required values are $A = 3, B = 1, C = 4$ .
