select the correct choice below and, if necessary, fill in the answer box to complete your choice.
a. the slope is
(type an integer or a simplified fraction.)
b. the slope is undefined.

Explanation:

Step1: Rewrite in slope - intercept form

The slope - intercept form of a line is $y = mx + b$, where $m$ is the slope and $b$ is the y - intercept. We start with the equation $2x - y=4$.
We want to solve for $y$. First, we can add $y$ to both sides of the equation: $2x=4 + y$. Then, we subtract 4 from both sides: $y=2x - 4$.

Step2: Identify the slope

In the equation $y = mx + b$, comparing $y = 2x-4$ with $y=mx + b$, we can see that $m = 2$.

Answer:

A. The slope is $2$
