Writing equations of lines parallel and perpendicular to a givell.. Consider the line -7x -3y=9. Find the equation of the line that is perpendicular to this line and passes through the point (-8, -3). Find the equation of the line that is parallel to this line and passes through the point (-8, -3). Note that the ALEKS graphing calculator may be helpful in checking your answer. Equation of perpendicular line: 0=0 Equation of parallel line: X
