Introduction

---

As a software designer working on a new racing game, you are tasked with mapping the streets of the game's virtual world. The streets are depicted as either perpendicular or parallel lines, and you need to determine the equation of the lane passing through two given points, A and B. In this article, we will explore the mathematical concepts involved in solving this problem and provide a step-by-step guide to finding the equation of the lane.

The Problem

---

The equation of the lane passing through points A and B is given by the linear equation:

$$-7x + 3y = c$$

where c is a constant. To find the equation of the lane, we need to determine the value of c.

Understanding Linear Equations

---

A linear equation is an equation in which the highest power of the variable(s) is 1. In this case, the equation is:

$$-7x + 3y = c$$

This equation can be rewritten in the slope-intercept form as:

$$y = mx + b$$

where m is the slope and b is the y-intercept.

Finding the Slope

---

To find the slope of the line passing through points A and B, we can use the formula:

$$m = \frac{y_2 - y_1}{x_2 - x_1}$$

where (x1, y1) and (x2, y2) are the coordinates of points A and B, respectively.

Finding the Equation of the Lane

---

Now that we have the slope, we can use it to find the equation of the lane. We can substitute the slope into the slope-intercept form of the equation:

$$y = mx + b$$

and then use the coordinates of points A and B to find the value of b.

Using the Coordinates of Points A and B

---

Let's assume that the coordinates of points A and B are (x1, y1) and (x2, y2), respectively. We can substitute these coordinates into the equation:

$$-7x + 3y = c$$

to get:

$$-7x_1 + 3y_1 = c$$

and

$$-7x_2 + 3y_2 = c$$

Solving for c

---

Now that we have two equations with the same value of c, we can solve for c by setting the two equations equal to each other:

$$-7x_1 + 3y_1 = -7x_2 + 3y_2$$

Simplifying the equation, we get:

$$-7(x_1 - x_2) = 3(y_2 - y_1)$$

Dividing Both Sides by -7

---

Dividing both sides of the equation by -7, we get:

$$x_1 - x_2 = -\frac{3}{7}(y_2 - y_1)$$

Substituting the Values of x1, x2, y1, and y2

---

Now that we have the equation, we can substitute the values of x1, x2, y1, and y2 to find the value of c.

Finding the Value of c

---

Substituting the values of x1, x2, y1, and y2 into the equation, we get:

$$c = -7x_1 + 3y_1$$

Substituting the Values of x1 and y1

---

Substituting the values of x1 and y1 into the equation, we get:

$$c = -7(2) + 3(5)$$

Simplifying the Equation

---

Simplifying the equation, we get:

$$c = -14 + 15$$

Finding the Value of c

---

Simplifying the equation further, we get:

$$c = 1$$

Conclusion

---

In this article, we have explored the mathematical concepts involved in solving the problem of finding the equation of the lane passing through points A and B. We have used the linear equation:

$$-7x + 3y = c$$

and the slope-intercept form of the equation:

$$y = mx + b$$

to find the equation of the lane. We have also used the coordinates of points A and B to find the value of c.

Final Answer

---

The final answer is:

$$c = 1$$

This is the value of c that we have found using the mathematical concepts and equations discussed in this article.
