5-92.

On graph paper, graph the line $y=\frac{3}{4}x+6$. Then find the slope angle (the acute angle the line makes with the $x\text{-axis}\$).

$\theta$ is the slope angle. Remember the slope is $\frac{3}{4}$ from $y=mx+b$ form.

Recall tangent of the slope angle is the slope.

$\text{tan}\theta=\text{slope}=\frac{3}{4}$
