Chapter 5.5, Problem 21P

Write each equation in standard form using integers.

$y=x-4$

To determine

To find: The standard form of the line equation $y=x-4$ .

Answer to Problem 21P

The standard form of the given equation is $-x+y=-4$ .

Explanation of Solution

Given information:

The equation is $y=x-4$ .

The equation can be rewritten in standard form as follows:

  $\begin{array}{l}y=x-4\\ \Rightarrow -x+y=-x+x-4\\ \Rightarrow -x+y=-4\end{array}$

Conclusion:

Therefore, the standard form of the given equation is $-x+y=-4$ .
