Question

Write each equation in standard form. Identify A, B and C.

$y=7x+15$

Short answer

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

Step-by-step solution

– Defining the standard form of linear equation

The standard form of linear equation is $Ax+By=C$.

– Simplifying the given equation

We have:

$y=7x+15$

Subtract $7x$ from both sides:

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

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

– Determining the final values

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