Solution
Solution Steps
Step 1: Identify the Slope
To find the slope of the line, we need to identify two points on the line. From the graph, we can see that the line passes through the points (0, 4) and (4, 0).
Step 2: Calculate the Slope
The slope \( m \) is calculated using the formula:
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]
Using the points (0, 4) and (4, 0):
\[ m = \frac{0 - 4}{4 - 0} = \frac{-4}{4} = -1 \]
Step 3: Write the Equation of the Line
The equation of a line in slope-intercept form is:
\[ y = mx + b \]
We already have the slope \( m = -1 \) and the y-intercept \( b = 4 \) (since the line crosses the y-axis at (0, 4)).
