1. Problem Description
The problem asks us to find the slope and y-intercept of the line shown in the graph and then write the equation of the line.
2. Solution Steps
First, let's identify two points on the line from the graph. From the graph, we can see the line passes through the points and .
The slope of the line passing through points and is given by:
Using the points and , we have:
The y-intercept is the point where the line crosses the y-axis, which is the y-coordinate when . From the graph, we can directly read the y-intercept as . Therefore, .
The slope-intercept form of a linear equation is:
where is the slope and is the y-intercept.
Substituting the values of and , we get:
The question asks for the slope only.
