The equation $y = 8$ $y = 8$ by definition is a horizontal line. For each and every possible value of $x$ $x$ $y$ $y$ is equal to $8$ $8$ .

By definition, the slope of a horizontal line is $m = 0$ $m = 0$

slope = $0$ $0$

Explanation:

One way is to graph the equation. You'll notice that it's a horizontal line that crosses the y-axis at $8$ $8$ . A horizontal line, by definition has a slope equal to $0$ $0$ .

Another way is to compare the equation to the slope-intercept form of a line:

$y = m x + b$ $y=mx+b$

where $m$ $m$ is the slope and $b$ $b$ is the y-intercept.

Since the equation we are given does not contain an $x$ $x$ we now that $m = 0$ $m=0$ . We also know that $b = 8$ $b=8$ . That is consistent with the graph, since the equation "intercepts" the y-axis at $8$ $8$ .
