To find the equation of the linear function
that is perpendicular to the line
and intersects it at
, we need to follow these steps:1. Find the slope of the given line
.2. Determine the slope of the perpendicular line
.3. Find the point of intersection at
.4. Use the point-slope form to write the equation of
.Step 1: Find the slope of the given line
.To find the slope, we can rewrite the equation in slope-intercept form
, where
is the slope.
The slope of the given line is
.Step 2: Determine the slope of the perpendicular line
.The slope of a line perpendicular to another line is the negative reciprocal of the original line's slope.The slope of the perpendicular line
is
.Step 3: Find the point of intersection at
.Substitute
into the equation of the given line to find the corresponding
-coordinate.
So, the point of intersection is
.Step 4: Use the point-slope form to write the equation of
.The point-slope form of a line is given by
, where
is a point on the line and
is the slope.Using the point
and the slope
, we can write the equation of
as:
Simplifying this equation, we get:
Therefore, the equation for the linear function
is:
