Introduction
In mathematics, finding the equation of a line that is perpendicular to a given line is a common problem.

Understanding the Problem
To find the equation of a line that is perpendicular to the given equation, we need to understand the concept of slope. The slope of a line is a measure of how steep it is. It is calculated as the ratio of the vertical change (rise) to the horizontal change (run) between two points on the line. The slope of the given line is 3, which means that for every unit increase in x, the value of y increases by 3 units.
Finding the Slope of the Perpendicular Line
The slope of the perpendicular line is the negative reciprocal of the slope of the given line. This means that if the slope of the given line is 3, the slope of the perpendicular line is -1/3. To find the equation of the perpendicular line, we need to use the formula , where is the slope of the perpendicular line.
