It seems you're working on a math assignment about lines and linear equations, covering topics like finding slopes, equations of lines, and systems of linear equations, along with a few problems on proportions. Here's a brief outline of the problems in the document:

Equations of Lines

1. Find the slope of the line passing through two points.
2. Find the equation of a line with a given slope and point.
3. Find the equation of a parallel line to a given equation.
4. Find the equation of a perpendicular line using two points.
5. Write the equation of a line in standard form with a given slope and y-intercept.

Systems of Linear Equations

6. Solve a system of equations.
7. Prove no solution exists for a system of equations.
8. Create a system with no solution by finding a specific line equation.
9. Create a system with infinite solutions by finding a matching line equation.

Proportions

10. Distance and time proportion: Calculate how far William can run in 20 minutes.
11. Pencil sales problem: Determine how many pencils can be bought with $4.00.
12. Car wash problem: Find how long it takes to wash 8 cars.
13. Fuel consumption problem: Calculate how far Jada can drive with 6.3 gallons of gas.

Would you like to work on solving any of these problems together? Let me know if you'd like details on any specific topic.

Here are five questions to expand on this:

1. How do you find the slope between two points?
2. What is the general formula for the equation of a line in slope-intercept form?
3. How can you determine if two lines are parallel?
4. What is the process for solving a system of linear equations?
5. How do you calculate proportions for real-world scenarios?

Tip:

When finding the equation of a line, always start with the slope-intercept form $y = mx + b$, where $m$ is the slope and $b$ is the y-intercept.
