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 (-8, 8) and (8, -8).
The formula for the slope (m) is:
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]
Using the points (-8, 8) and (8, -8):
\[ m = \frac{-8 - 8}{8 - (-8)} = \frac{-16}{16} = -1 \]
Step 2: Determine the Y-Intercept
The y-intercept (b) is the point where the line crosses the y-axis. From the graph, we can see that the line crosses the y-axis at (0, 0).
Thus, the y-intercept (b) is 0.
Step 3: Write the Equation of the Line
Using the slope-intercept form of the equation of a line, which is:
\[ y = mx + b \]
Substituting the slope (m = -1) and the y-intercept (b = 0):
\[ y = -1x + 0 \]
\[ y = -x \]
