Write the equation in slope-intercept form of the line graphed.
The equation of the line is $\square$ .
(Simplify your answer. Type your answer in slope-intercept form. Use integers or fractions for any numbers in the expression.)
Solution
Solution Steps
Step 1: Identify two points on the line
From the graph, we can identify two points on the line. Let's use the points (2, 2) and (0, 6).
Step 2: Calculate the slope (m)
The slope \( m \) is calculated using the formula:
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]
Using the points (2, 2) and (0, 6):
\[ m = \frac{6 - 2}{0 - 2} = \frac{4}{-2} = -2 \]
Step 3: Use the slope-intercept form equation
The slope-intercept form of a line is:
\[ y = mx + b \]
We already have \( m = -2 \). To find \( b \), we use one of the points, say (0, 6):
\[ 6 = -2(0) + b \]
\[ b = 6 \]
Final Answer
The equation of the line in slope-intercept form is:
\[ y = -2x + 6 \]
