The equation of the line in slope-intercept form is .

Solution

To write the equation of a line in slope-intercept form, we use the formula:
where:
  • is the slope of the line.
  • is the -intercept, which is the point where the line crosses the -axis.
Given:
  • Slope ( ):
  • -intercept ( ):
Plugging these values into the slope-intercept formula:
Final Equation:

The equation of a line in slope-intercept form is given by , where is the slope and is the -intercept. For the given line, the slope is and the -intercept is . Plugging in these values, we get:
This means that for every 2 units you move to the right, the line drops 1 unit down.
Understanding slopes and intercepts can be crucial for interpreting and modeling real-world phenomena, such as predicting costs or analyzing trends. For example, if this line represented cost over time, you could interpret the -intercept as the initial cost and the slope as how quickly cost decreases as time goes on. Such insights can help businesses make data-driven decisions!
