If the lines whose equations are `y=m_1 x+ c_1 , y = m_2 x + c_2 and y=m_3 x + c_3 ` meet in a point, then prove that : `m_1 (c_2 - c_3) + m_2 (c_3 - c_1) + m_3 (c_1 - c_2) =0`

If three lines whose equations are y = m_1x + c_1 , y = m_2x + c_2 and y = m_3x + c_3 are concurrent, then show that m_1(c_2 - c_3) + m_2 (c_3 -c_1) + m_3 (c_1 - c_2) = 0 .

If three lines whose equations are y = m_1x + c_1,y = m_2x + c_2 and y= m_3x + c_3 are concurrent, then show that m_1(c_2-c_3) + m_2(c_3-c_2)+m_3(c_1-c_2) = 0

If three lines whose equations are y=m_(1) x+c_(1), y=m_(2) x + c_(2) and y=m_(3) x + c_(3) are concurrent, then show that m_(1) (c_(2) - c_(3))+m_(2) (c_(3) - c_(1) ) + m_(3) ( c_(1) - c_(2) ) =0 .

If three lines whose equations are y =m_1 x+c_1, y=m_2 x+c_2 and y=m_3 x+c_3 are concurrent, then show that m_1(c_2-c_3)+m_2(c_3-c_1)+m_3(c_1-c_2)=0
