Introduction

In mathematics, finding the equation of a line that is parallel to another line and passes through a given point is a fundamental problem in geometry and algebra. In this article, we will discuss how to find the equation of a line that is parallel to the line $x = 7$ and passes through the midpoint of the segment joining the points $(1, 6)$ and $(5, -5)$.

Understanding the Problem

To find the equation of a line that is parallel to the line $x = 7$, we need to understand the concept of parallel lines. Two lines are said to be parallel if they have the same slope. The line $x = 7$ is a vertical line, which means it has an undefined slope. Therefore, any line that is parallel to the line $x = 7$ will also be a vertical line.

Finding the Midpoint of the Segment Joining $(1, 6)$ and $(5, -5)$

To find the equation of the line that passes through the midpoint of the segment joining the points $(1, 6)$ and $(5, -5)$, we need to find the coordinates of the midpoint. The midpoint formula is given by:

$$\left(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}\right)$$

where $(x_1, y_1)$ and $(x_2, y_2)$ are the coordinates of the two points.

Plugging in the values, we get:

$$\left(\frac{1 + 5}{2}, \frac{6 + (-5)}{2}\right) = \left(\frac{6}{2}, \frac{1}{2}\right) = (3, 0.5)$$

Finding the Equation of the Line

Since the line is parallel to the line $x = 7$, it will also be a vertical line. Therefore, the equation of the line will be of the form $x = a$, where $a$ is a constant.

Since the line passes through the midpoint $(3, 0.5)$, we can substitute these values into the equation to find the value of $a$.

$$x = a$$

$$3 = a$$

Therefore, the equation of the line is $x = 3$.

Conclusion

In this article, we discussed how to find the equation of a line that is parallel to the line $x = 7$ and passes through the midpoint of the segment joining the points $(1, 6)$ and $(5, -5)$. We found that the equation of the line is $x = 3$.

Understanding the Concept of Parallel Lines

Parallel lines are lines that have the same slope. In the case of the line $x = 7$, it is a vertical line, which means it has an undefined slope. Therefore, any line that is parallel to the line $x = 7$ will also be a vertical line.

Finding the Equation of a Line Passing Through a Given Point

To find the equation of a line passing through a given point, we need to use the point-slope form of the equation of a line. The point-slope form is given by:

$$y - y_1 = m(x - x_1)$$

where $(x_1, y_1)$ is the given point and $m$ is the slope of the line.

Finding the Slope of a Line

The slope of a line can be found using the formula:

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

where $(x_1, y_1)$ and $(x_2, y_2)$ are two points on the line.

Finding the Equation of a Line Passing Through Two Points

To find the equation of a line passing through two points, we can use the two-point form of the equation of a line. The two-point form is given by:

$$y - y_1 = \frac{y_2 - y_1}{x_2 - x_1}(x - x_1)$$

where $(x_1, y_1)$ and $(x_2, y_2)$ are the two points on the line.

Conclusion

In this article, we discussed how to find the equation of a line that is parallel to the line $x = 7$ and passes through the midpoint of the segment joining the points $(1, 6)$ and $(5, -5)$. We found that the equation of the line is $x = 3$. We also discussed the concept of parallel lines, finding the equation of a line passing through a given point, finding the slope of a line, and finding the equation of a line passing through two points.

Final Answer

The final answer is $x = 3$.
