Chapter 2: Q20. (page 101)

Write each equation in standard form. Identify A, B and C.
$y = 7 x + 15$

Short Answer

Expert verified

The value of $A = - 7, B = 1, C = 15$

Step by step solution

01

– Defining the standard form of linear equation

The standard form of linear equation is $A x + B y = C$ .

02

– Simplifying the given equation

We have:

$y = 7 x + 15$

Subtract $7 x$ from both sides:

\begin{array}{l} y - 7 x = 7 x - 7 x + 15 \\ y - 7 x = 15 \\ - 7 x + y = 15 \end{array}

$∴ A = - 7, B = 1, C = 15$

03

– Determining the final values

$A = - 7, B = 1, C = 15$
