Step 1.2.2.1.1

Cancel the common factor.

$\frac{8 y}{8} = \frac{3 x}{8} + \frac{9}{8}$

Step 1.2.2.1.2

Divide $y$ by $1$ .

$y = \frac{3 x}{8} + \frac{9}{8}$

Step 1.3

Reorder terms.

$y = \frac{3}{8} x + \frac{9}{8}$

Step 2

Using the slope-intercept form, the slope is $\frac{3}{8}$ .

$m = \frac{3}{8}$
