Math Problem Statement
Solution
To find the equation of the line in slope-intercept form, we need to determine the slope (m
) and the y-intercept (b
).
Step 1: Identify two points on the line
From the graph:
- The line appears to pass through the points and .
Step 2: Calculate the slope (m
)
The slope is calculated using the formula:
Substituting the points and into the formula:
Step 3: Determine the y-intercept (b
)
The slope-intercept form is:
We can use one of the points to solve for . Let's use the point :
Step 4: Write the final equation
The equation of the line in slope-intercept form is:
