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

Rewrite the equation $\"\"$ in the slope - intercept form: $\"\"$ where m is slope and b is y - intercept.

Add 8x to each side.

$\"\"$

Divide each side by 9.

$\"\"$ .

Therefore slope of given line is $\"\"$ .

Because the slopes of perpendicular lines are negative reciprocals, the slope of perpendicular line through $\"\"$ is $\"\"$ .

To find the y - intercept of perpendicular line, substitute the values of $\"\"$ in the slope - intercept from: $\"\"$ and solve for b.

$\"\"$

$\"\"$ .

Substitute the values of $\"\"$ in the slope - intercept form of equation $\"\"$ .

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