To find the equation of the line that passes through the point
and is perpendicular to the line
, we need to follow these steps:1. Find the slope of the given line
.2. Find the slope of the line perpendicular to the given line.3. Use the point-slope form of a linear equation to find the equation of the perpendicular line.Step 1: Find the slope of the given line
.The given line can be rewritten in slope-intercept form as
. The slope of this line is
.Step 2: Find the slope of the line perpendicular to the given line.The slope of a line perpendicular to another line is the negative reciprocal of the slope of the original line. Therefore, the slope of the line perpendicular to the given line is
.Step 3: Use the point-slope form of a linear equation to find the equation of the perpendicular line.The point-slope form of a linear equation is
, where
is a point on the line and
is the slope.Substituting the point
and the slope
into the point-slope form, we get:
Simplifying this equation, we get:
Therefore, the equation of the line that passes through the point
and is perpendicular to the line
is
.
