Math Problem Statement
Solution
This graph shows a straight line with a negative slope, indicating that as increases, decreases. Let's determine the slope and the equation of the line.
1. Slope Calculation
To find the slope , we can use two points the line passes through. From the graph, the line passes through:
- Point
- Point
The formula for slope is:
Substituting the points and :
2. Equation of the Line
The slope-intercept form of a line is:
Using the slope and one point, let's substitute point into the equation to find (the y-intercept):
Simplifying:
Thus, the equation of the line is:
Summary:
- Slope:
