Math Problem Statement
Solution
To write the equation of the line in slope-intercept form , let's analyze the graph shown in your image.
Step 1: Identify two points on the line.
From the graph, it looks like two points the line passes through are:
- (the y-intercept)
Step 2: Calculate the slope .
The slope formula is: Using the two points and :
Step 3: Write the equation in slope-intercept form.
We know the slope and the y-intercept (since the line crosses the y-axis at ).
Thus, the equation of the line is:
This is the slope-intercept form of the equation for the given line.
Let me know if you have any questions! Here are a few related questions:
- How do you find the slope if the points are negative?
- What if the y-intercept is a fraction?
- How do you convert slope-intercept form to standard form?
- What is the significance of slope in real-world contexts?
- How would the equation change if the line had a negative slope?
Tip: Always double-check your points and slope calculations to avoid sign errors.
