Math Problem Statement
Graph the line: y = -3x - 3
Solution
The equation provided is , and you are asked to graph the line.
This is a linear equation in slope-intercept form: , where:
- is the slope of the line
- is the y-intercept.
For :
- The slope , meaning that for every 1 unit increase in , the value of decreases by 3.
- The y-intercept , meaning the line crosses the y-axis at .
Steps to graph the line:
- Start with the y-intercept: Plot the point on the graph. This is where the line crosses the y-axis.
- Use the slope: The slope is , or . This means you move 1 unit to the right along the x-axis and 3 units down along the y-axis from the y-intercept.
- From , move right to and plot this point.
- Extend the line: Continue applying the slope or use another approach (e.g., symmetry or plotting more points) to extend the line in both directions.
- Draw the line: Connect the points to form a straight line.
Would you like me to generate the graph or further explain any of these steps?
Here are five related questions to deepen your understanding:
- How does the slope of the line affect its steepness?
- What is the significance of the y-intercept in a real-world scenario?
- How would the graph change if the slope were positive?
- Can you determine the x-intercept for this line?
- How do parallel and perpendicular lines relate in terms of their slopes?
Tip: Always check the sign of the slope to know whether the line will incline upward or downward as you move from left to right.
