The problem asks us to find the slope and y-intercept of the given line. The slope is provided as -9. Then, we need to use the slope and y-intercept to write the equation of the line.

1. Problem Description

The problem asks us to find the slope and y-intercept of the given line. The slope is provided as -

9. Then, we need to use the slope and y-intercept to write the equation of the line.

2. Solution Steps

First, let's find the y-intercept. From the graph, we can see that the line intersects the y-axis at y =

1

2. Therefore, the y-intercept is

1

2.

The slope-intercept form of a line is given by:

$y = mx + b$

where $m$ is the slope and $b$ is the y-intercept.

We are given the slope $m = -9$ and we found the y-intercept $b = 12$.

Substituting these values into the slope-intercept form, we get:

$y = -9x + 12$

3. Final Answer

$y = -9x + 12$
