Answer
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!
