A line k passes through the points (4,2) and (-4,4). A second line h passes through the points (-8,1) and (8, -3). Is line k parallel to line h? Why or why not?

Question

A line k passes through the points (4,2) and (-4,4).  A second line h passes through the points (-8,1) and (8, -3).  Is line k parallel to line h?  Why or why not?

anonymous · Answer

slope of line k = 2/-8 = -1/4

slope of line h = -4/16 = -1/4

both slope are equal , so both lines are parallel
