    product of a slope?????? if two lines are perpendicular then the product of their slope is -1.

    If you have a pair of lines, you can find their slopes by rearranging each line into "slope-intercept" form, which is \[y = mx+b\]where \(m\) is the slope and \(b\) is the \(y\)-intercept. Having found the slope for the first line (call it \(m_1\)) and the second line (call it \(m_2\)) you find the product of the slopes by simply multiplying them together... \(m_1 * m_2\) The most frequent reason for wanting to know this is to determine if the lines are perpendicular. A pair of perpendicular lines will have a product of their slopes which equals \(-1\), except in the case where one line is vertical \(y = k_1\) and the other is horizontal \(x = k_2\) (\(k_1, k_2\) are constants)
