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 1.2.1.1

Apply the distributive property.

$y = \sin (x) \cos (x) + \sin (x) \cdot 1$

Step 1.2.1.2

Multiply $\sin (x)$ by $1$ .

$y = \sin (x) \cos (x) + \sin (x)$

Step 2

The equation is not linear, so a constant slope does not exist.
