Math Problem Statement
Graph the linear equation y = -5x + 7.
Solution
The equation provided in the image is . This is the equation of a straight line in slope-intercept form, where:
- The slope () is .
- The y-intercept () is .
Steps to Graph:
- Plot the y-intercept: Start at on the y-axis.
- Use the slope to find another point:
- Slope means that for every 1 unit increase in , decreases by 5.
- From , move 1 unit to the right (), and then move 5 units down (). This gives a second point, .
- Draw the line: Connect these points and extend the line in both directions.
Let me know if you'd like me to graph it for you or explain any step further.
Would you like a detailed graph? Here are related questions for practice:
- How do you find the slope of a line given two points?
- What happens to the graph if the slope is positive instead of negative?
- How would the graph change if the equation were ?
- How can you determine the x-intercept of a line?
- How do you graph a line when the equation is not in slope-intercept form?
Tip: Always identify the y-intercept and slope first to make graphing easier!
