To find parallel and perpendicular lines:

01) The slope of a line is 3/2. What is the slope of any line parallel to this line?

02) The slope of a line is -4/5. What is the slope of any line perpendicular to this line?

Two lines are parallel if their slopes are equal, $\displaystyle m_1=m_2.$

Two lines are perpendicular if their product is $\displaystyle -1,$ this is $\displaystyle m_1\cdot m_2=-1.$ - Nov 1st 2007, 09:23 AMThePerfectHacker
