Step 2

Rewrite in slope-intercept form.

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

$y = m x + b$

Reorder $\frac{3}{4}$ and $- \frac{3 x}{2}$ .

Find the values of $m$ and $b$ using the form $y = m x + b$ .

$m = - \frac{3}{2}$

$b = \frac{3}{4}$

The slope of the line is the value of $m$ , and the y-intercept is the value of $b$ .

Slope: $- \frac{3}{2}$

y-intercept: $(0, \frac{3}{4})$

Slope: $- \frac{3}{2}$

y-intercept: $(0, \frac{3}{4})$
