Step 1.2.1.1

Combine $x$ and $\frac{5}{4}$ .

$y = - \frac{x \cdot 5}{4} - 8$

Step 1.2.1.2

Move $5$ to the left of $x$ .

$y = - \frac{5 x}{4} - 8$

Step 1.3.1

Reorder terms.

$y = - (\frac{5}{4} x) - 8$

Step 1.3.2

Remove parentheses.

$y = - \frac{5}{4} x - 8$

Step 2

Using the slope-intercept form, the slope is $- \frac{5}{4}$ .

$m = - \frac{5}{4}$
