Step 1.1

The slope-intercept form is $y = m x + b$ , where $m$ is the slope and $b$ is the y-intercept.

$y = m x + b$

Step 1.2

Simplify the left side.

Step 1.2.1

Multiply $y$ by $1$ .

$5 x + y = 16$

Step 1.3

Subtract $5 x$ from both sides of the equation.

$y = 16 - 5 x$

Step 1.4

Reorder $16$ and $- 5 x$ .

$y = - 5 x + 16$

Step 2

Using the slope-intercept form, the slope is $- 5$ .

$m = - 5$
