Math Problem Statement
Solution
Let's go through each of these equations and rewrite them in the form (slope-intercept form), so they can be easily graphed:
16.
- Slope
- Y-intercept
This line has a slope of 1, meaning it rises 1 unit for every 1 unit it moves to the right. It crosses the y-axis at 2.
18.
- Slope
- Y-intercept
This line has a slope of , meaning it rises 1 unit for every 2 units it moves to the right. It crosses the y-axis at -1.
20.
First, solve for : Distribute:
- Slope
- Y-intercept
This line has a slope of , meaning it rises 1 unit for every 3 units it moves to the right. It crosses the y-axis at 2.
22.
First, solve for :
- Slope
- Y-intercept
This line has a slope of 1 and crosses the y-axis at -9.
Do you want to go through the graphing process in more detail or have any specific questions on these lines?
Here are five related questions:
- How do you calculate the slope of a line from two points?
- What does the slope represent in real-world applications?
- How can you find the x-intercept of a line?
- What happens to the graph of a line when you change its slope?
- How does changing the y-intercept affect the position of the line?
Tip: Always check if a line passes through the origin by setting and solving for .
