The equation of the line is $\"\"$ . \ \

The point is $\"\"$ .

$\"\"$

Because the slope of the line is $\"\"$ , the slope of the perpendicular line is the \ \

negative reciprocal of $\"\"$ , or $\"\"$ .

The perpendicular line passes through $\"\"$ , so its y-intercept is $\"\"$ .

The equation of the line is $\"\"$ .
