Transcript text: Question
Write the equation of the line in fully simplified slope-intercept form.
Solution
Solution Steps
Step 1: Identify two points on the line
From the graph, we can identify two points on the line. Let's choose the points (-8, 8) and (4, -4).
Step 2: Calculate the slope (m)
The slope \( m \) is calculated using the formula:
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]
Substituting the points (-8, 8) and (4, -4):
\[ m = \frac{-4 - 8}{4 - (-8)} = \frac{-12}{12} = -1 \]
Step 3: Use the slope-intercept form to find the y-intercept (b)
The slope-intercept form of a line is:
\[ y = mx + b \]
Using one of the points, say (-8, 8), and the slope \( m = -1 \):
\[ 8 = -1(-8) + b \]
\[ 8 = 8 + b \]
\[ b = 0 \]
Final Answer
The equation of the line in fully simplified slope-intercept form is:
\[ y = -x \]
