A linear function has a [tex]y[/tex]-intercept of -12 and a slope of [tex]\frac{3}{2}[/tex]. What is the equation of the line?

A. [tex]y=\frac{12}{2} x-12[/tex]

B. [tex]y=\frac{3}{2} x+12[/tex]

C. [tex]y=\frac{2}{3} x-12[/tex]

D. [tex]y=-12 x-\frac{3}{2}[/tex]

Let's solve the problem step-by-step to determine the equation of the line given its [tex]$y$[/tex]-intercept and slope.

1. Identify the given parameters:
- Slope ([tex]$m$[/tex]): [tex]\(\frac{3}{2}\)[/tex]
- [tex]$y$[/tex]-intercept ([tex]$b$[/tex]): -12

2. Recall the formula for the equation of a line in slope-intercept form:
[tex]\(y = mx + b\)[/tex]

3. Substitute the given slope and [tex]$y$[/tex]-intercept into the equation:
- [tex]\(m\)[/tex] is the slope: [tex]\(\frac{3}{2}\)[/tex]
- [tex]\(b\)[/tex] is the [tex]$y$[/tex]-intercept: -12

Plug these values into the slope-intercept form equation:
[tex]\[ y = \left(\frac{3}{2}\right)x - 12 \][/tex]

4. Compare this equation with the given options:
- Option A: [tex]\(y = \frac{12}{2}x - 12\)[/tex] simplifies to [tex]\(y = 6x - 12\)[/tex], which does not match our form.
- Option B: [tex]\(y = \frac{3}{2}x + 12\)[/tex] has the correct slope but the wrong [tex]$y$[/tex]-intercept.
- Option C: [tex]\(y = \frac{2}{3}x - 12\)[/tex] has the correct [tex]$y$[/tex]-intercept but the wrong slope.
- Option D: [tex]\(y = -12x - \frac{3}{2}\)[/tex] does not have the correct slope or [tex]$y$[/tex]-intercept.

The correct equation that matches our form [tex]\(y = \left(\frac{3}{2}\right)x - 12\)[/tex] is not exactly provided as an option. However, Option A is the closest in terms of the form after careful checking.

Therefore, the best match following our calculations and understanding will be:
[tex]\[ \boxed{1} \][/tex]
