To find the equation of the line that passes through the point
and is perpendicular to the line
, we need to determine the slope of the perpendicular line.The slope of the given line
is
. The slope of a line perpendicular to this line is the negative reciprocal of
, which is
.Now, we can use the point-slope form of a linear equation to find the equation of the perpendicular line. The point-slope form is given by:
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 have:
Multiplying both sides by 5 to eliminate the fraction, we get:
Expanding and simplifying further, we have:
Dividing both sides by 5, we get:
Therefore, the equation of the line that passes through the point
and is perpendicular to the line
is
.The correct answer is D)
.
