Solution
To find the x-intercept and y-intercept of the line shown in the graph:
-
x-intercept: The x-intercept is the point where the line crosses the x-axis, which means . From the graph, we can see that the line crosses the x-axis at . Hence, the x-intercept is .
-
y-intercept: The y-intercept is the point where the line crosses the y-axis, which means . From the graph, the line crosses the y-axis at . Hence, the y-intercept is .
Summary:
- (a) x-intercept:
- (b) y-intercept:
Would you like further clarification on this? Here are a few follow-up questions to expand on this topic:
- How do you find the slope of the line from this graph?
- What is the equation of the line based on the intercepts and slope?
- Can you explain why the y-intercept happens when ?
- How would the graph change if the slope were negative?
- How do you find intercepts for non-linear functions like parabolas?
Tip: The x-intercept and y-intercept are key points for any linear equation and can help quickly sketch the graph of the line.
