The document contains a set of mathematical problems involving algebra and geometry. Here’s a breakdown of the questions for clarity:

1. Find the slope of the line that passes through the points (7, -2) and (-9, 5).
2. Graph the function by finding the x- and y-intercepts of $x = -3y$.
3. Graph the intersection of two inequalities: $-2x + y \leq 5$ and $x - y \geq -2$.
4. Find an equation of a line that is perpendicular to $5x - 7y = 5$ and passes through (3, 4). The equation should be written in standard form.
5. Write the equation of a line with a slope of -3 that passes through the point (-7, -3). The equation should be in slope-intercept form $y = mx + b$.
6. Graph the function by finding the x- and y-intercepts of $x - 24y = 24$.
7. Solve the word problem: The cost of a tow truck service is modeled by the linear function $y = 2x + 80$, where $y$ is the cost in dollars and $x$ is the number of miles towed. Interpret the slope and y-intercept of this linear equation.

Would you like a solution to all the questions, or is there a specific one you'd like to start with?

Here are 5 related questions for practice:

1. How do you calculate the slope between two points?
2. What is the process to find x- and y-intercepts from an equation?
3. How can you graph systems of inequalities?
4. How do you determine the equation of a perpendicular line?
5. How is the slope of a line interpreted in word problems?

Tip: To find the slope of a line through two points $(x_1, y_1)$ and $(x_2, y_2)$, use the formula $m = \frac{y_2 - y_1}{x_2 - x_1}.$
