    What do you know about the slopes of perpendicular lines?

    The slopes of perpendicular lines are negative reciprocals. That means that when you multiply together the slopes of two perpendicular lines, you get -1.

    Here is the equation of a line in standard form: \(ax + by = k\) We solve it for y to get it in slope-intercept form. \(by = -ax + k\) \(y = -\dfrac{a}{b}x + \dfrac{k}{b} \) The slope-intercept form is \(y = mx + b\), where m is the slope. That means, to find the slope using the standard form, just find \(-\dfrac{a}{b} \). Take the given equation and each of the choices, and find \(-\dfrac{a}{b} \). Then find which choice has a slope that is not the negative reciprocal of the slope of the given equation.
