Solution
The image provided shows the equation of a line and asks for the equations of a line parallel to it and a line perpendicular to it, passing through a given point.
The given equation of the line is:
1. Equation of the Parallel Line
A line parallel to the given line will have the same slope. The slope of the given line is . We need to find the equation of the line parallel to this one that passes through the point .
Using the point-slope form of the equation of a line:
where is the slope and is the point ,
Simplifying:
Subtract 5 from both sides:
Convert to a fraction with a denominator of 2:
Thus, the equation of the line parallel to the given line is:
2. Equation of the Perpendicular Line
A line perpendicular to the given line will have a slope that is the negative reciprocal of the slope of the original line. The slope of the given line is , so the slope of the perpendicular line will be:
Using the point-slope form again with the point :
Simplifying:
Subtract 5 from both sides:
Convert to a fraction with a denominator of 7:
Thus, the equation of the line perpendicular to the given line is:
