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
.To find the slope of the given line, we need to rewrite it in slope-intercept form, which is
, where
is the slope and
is the y-intercept.
The slope of the given 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.The slope of the given line is
, so the slope of the perpendicular 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.We are given the point
and the slope
, so we can substitute these values into the point-slope form:
Now, we can simplify this equation:
Therefore, the equation of the line that passes through the point
and is perpendicular to the line
is
.
