Math Problem Statement
Write the equation of a line that is parallel to [{y=-7}] and that passes through the point [{(7,5)}].
Solution
The given equation of the line is:
This represents a horizontal line at . A line parallel to it must also be horizontal, meaning it will have the same form:
Since the new line passes through the point , its equation is:
Final Answer:
Would you like a detailed explanation on why parallel horizontal lines have the same form?
Here are five related questions to explore further:
- What is the equation of a line perpendicular to passing through ?
- How do you find the equation of a line parallel to a given vertical line?
- How do you determine the slope of a horizontal and vertical line?
- Can a horizontal line ever be written in point-slope form?
- How do you find the distance between two parallel horizontal lines?
Tip: The slope of a horizontal line is always zero because it does not rise or fall as changes.
