     The slopes of four lines are indicated in the figure. List the slopes m_1, m_2, m_3, m_4 in order of increasing value.  a. m_3, m_4, m_1, m_2  b. m_3, m_4, m_2, m_1  c. m_2, m_1, m_3, m_4  d. m_1, m_3, m_4, m_2  e. m_4, m_2, m_1, m_3 
  
  Solution
slope of m2 is zero
slope of m1 is highly positive
slope of m3 is highly negative
slope of m4 is negative
increasing order of slopes is m3,m4,m2,m1
