Math Problem Statement
Graph the line: y = 3x - 8
Solution
The equation provided is , which is in slope-intercept form , where:
- is the slope, meaning the line rises 3 units for every 1 unit it moves to the right.
- is the y-intercept, meaning the line crosses the y-axis at .
To graph this line:
- Start by plotting the y-intercept, .
- Use the slope to find another point: From , move 1 unit to the right (along the x-axis) and 3 units up. This gives the point .
- Draw a line through these two points.
Would you like me to provide further details or explanations?
Here are five related questions to expand this topic:
- How do you determine the slope from a line given two points?
- What does it mean when the slope of a line is negative?
- How can you find the x-intercept of a linear equation?
- What happens to the graph if the slope becomes smaller, such as ?
- Can a linear equation have no y-intercept?
Tip: The slope of a line describes its steepness. A higher slope means a steeper line, while a smaller slope results in a flatter line.
