Note that the given equation is in slope-intercept form. That means that the slope of the line represented by the given equation is available by inspection of the coefficient on . Perpendicular lines have slopes that are negative reciprocals, i.e.
So calculate the slope of the desired line by taking the negative reciprocal of the slope of the line represented by the given equation.
Use the point-slope form of an equation of a line:
where are the coordinates of the given point and is the calculated slope.
Do the indicated arithmetic and simplify. Put the result in a form to match your list of answers.
