The equation of the line parallel to
that passes through
is
.
Solution
To find the equation of a line that is parallel to the given line and passes through a specific point, follow these steps:
-
Identify the Slope of the Given Line:The given line is
. The slope ( ) of this line is . -
Formulate the Equation of the Parallel Line:Since parallel lines have the same slope, the equation of the desired line will also have a slope of
. Thus, the equation will be of the form: whereis the y-intercept we need to determine. -
Use the Given Point to Find

Beyond the Answer
To find a line parallel to
, we need to remember that parallel lines have the same slope. So, our new line will also have a slope of
. Now, we can use the point-slope form of a line, which starts with
. Using the point
and the slope
, we can derive the equation of the line.
Plugging in the values, we have:
This simplifies to:
Therefore,
This simplifies to:
Therefore,
Thus, the line that is parallel to the original and passes through the point
is option D:
.
This hints at how geometry and algebra can work hand-in-hand! In real-world applications, the concept of parallel lines is essential, especially in fields like engineering, architecture, and even in art, where maintaining straight lines or levels is vital for structural integrity and aesthetic appeal.
Additionally, it’s fascinating to note that many programming and computer graphics algorithms utilize linear equations to create realistic simulations and graphics. Everything we see on a screen, from the simplest 2D shapes to complex 3D models, often stems from these foundational concepts of lines and coordinates!
